graphing calculator for calculus

Are you a student that is looking for a calculator that you can rely on during your Calculus adventure? Today, I will be reviewing the The HP 50g graphing calculator. An easy to use, affordable and dependable graphing calculator for Calculus and other math subjects as well. So, let’s start the short review now. In fact, this graphing calculator is in the Top Graphing Calculators List by Calcustar.

Why The HP 50g is the best graphing calculator for calculus?


  1. 2000+ built in functions
  2. CAS (computer algebra system) included
  3. for nearly 50 dollars less than the next best competitor (the TI nSpire CX CAS)
  4. 3-way connectivity through various ports (including infrared for wireless communication)
  5. SD Card functionality for increased memory
  6. Function editor

Ease of Use

hp-calcu2The HP 50g graphing calculator contains an easily accessible keyboard with color coded buttons for both functions and numbers. The keypad layout is similar to that of both Texas Instruments and Casio calculators; however, one of the major differences is that lack of a SHIFT or 2ND key.

These keys are replaced by a white arrow and an orange arrow, which both lead to two different functions labeled above the main buttons. This saves even more time, since more functions are able to be “shortcutted” through the main keypad without need to use the menus.

The HP 50g has a very interesting key recognition: if you press a key before letting go of the other, it will recognize both key presses. However, if you press the same key twice very quickly to type a number such as “33”, it will only register the first press for 3, which can be frustrated when inputting long strings.


The HP 50g has a compact boxy design and grayscale screen, both designed to be resistant to daily wear and tear. This means resistance to falls, drops, and impacts against hard surfaces. The only parts of the calculator that require replacement are its batteries, and/or optional SD card.


Due to the increased workload of the CAS system, the HP 50g boasts a 2.5 MB combined memory. Furthermore, the memory is able to be boosted in the future if required with a SD card.

hp-calcu3This calculator is able to conduct lightning fast calculations, perfect for any student or professional. However, the real question is whether it is able to beat the titan of graphing calculators: the TI nSpire CX CAS, which is also good for AP Calculus. When solving the same integral, the TI nSpire indeed showed a faster solve time of about a tenth a second.

This may not seem like much, but after conducting tens of thousands of calculations, the time saved translates into hours. The choice to save money or save time is up to you.

Otherwise, for basic and intermediate functions, the HP 50g works flawlessly. This makes it a great choice for classroom use in algebra and calculus classes.


This is the most updated version of HP graphing calculators, succeeding the 48/49 models. HP boasts a large amount of information on its website, but there are fewer independent support networks than Texas Instruments or Casio. Users also report the included physical user manual of the calculator to be difficult to understand and navigate.


  • ROM: 2MB
  • RAM: 512 kilo
  • Screen: 131 pixels by 80 pixels, high contrast grayscale
  • Power: 4 AAA batteries + button battery
  • Programmable: Yes
  • Tests: Usable for many standardized tests


For students who are looking for a high performance calculator with CAS for a discount price, the HP 50g is the perfect option. For heavier usage in problem solving and analysis, the nSpire may be a better choice. Nevertheless, you will surely love the HP 50g and save more money.

Lower Back Pain During Pregnancy

back pain in pregnancy

Lower back pain during pregnancy can be frustrating and difficult. The body has undergone so many changes that it sometimes feels like you are dealing with an annoying cold. It seems like there is some part that is always feeling uncomfortable. Sleep is dreadful, especially having to get out of bed. All in all, there comes a point when you just want the baby out!

Not all of the different twinges are uncomfortable. Pregnant mothers tend to love the feel of the baby’s kicks, especially at first. They can become somewhat awkward as the baby gets bigger, but most of the time, the kicks are enjoyed. It is a way to connect with the baby growing inside. However, these kicks can cause lower back pain during pregnancy.

The other reason lower back pain and discomfort is felt is how the body gains weight. When a 125-pound woman puts on 25 to 30 pounds, she is going to feel every pound towards the end. Plus, the center of gravity changes, as more weight is centered in front of the body. This will change how you walk, sit, sleep, and everything else you do in life. Because of this discomfort, there are some things you can do to ease the lower back pain during pregnancy.

The main thing is to start doing several exercises that will help relieve some of the pain. This also helps strengthen the core muscles, relieving some of the back strain. It will also help to do some moderate exercise, especially if you did it prior to pregnancy. You just have to be careful not to do too much, especially as the weight continues to shift. Another idea is to walk correctly, keeping the shoulders back and the hips aligned under the feet. Another perfect solution for back pain is using only the best pregnancy body pillow available in the market.

If you are standing for a period of time, try to shift the weight back and forth from foot to foot. When you are sitting, you need to keep the lower back supported and the feet on the ground. If you follow these techniques, you can ease some of the lower back pain during pregnancy. If you want to look good and feel great, then you should take a look at Pregnancy Without Pounds books. It will help you to stop gaining unnecessary pregnancy weight and get through pregnancy feeling fit, toned and healthy.

5 Things that Will Become Obsolete in Math and Science by 2025


There are many lists going around concerning what the next decade will bring in K-12 education, especially focusing on those things that will become obsolete. Well, I decided to create my own list of 5 things that should become obsolete in K-12 education by 2025.

Standardized Tests

SAT and ACT tests do not carry the weight they use to for college admission. All standardized testing associated with the No Child Left Behind Act (NCLB) is pretty much worthless, only good for politicians and determining a student’s ability to pass a test on a given day.

Standardized testing and NCLB have transformed many schools into testing machines that take the inquisitiveness out science and math by turning our children into bored, underachieving test taking robots. This is a sad thing, I really love my new graphing calculator.


The United States continues to fall behind most Asian and some European countries in science and math (Third International Science and Math Study, 2007).One interesting fact that jumps out about these countries is that they continually outscore the United States – while requiring little or no homework.Homework is a staple in this country.

Because of this parents often think their children’s teachers are not very good unless they send home a regular amount of homework. The biggest problem concerning homework — students who do not understand in school, will still not understand at home.

Also, parents are forced into the position of teaching their child something that they themselves may know little about – especially in science and math. For the record — My definition of homework is repetitious math problems and memorization of science terms, along with the rote memorization of math and science facts.

Computer Labs

This is one of the biggest wastes of technology resources in schools today. Computers belong in the classroom! I have been in schools where computers are connected to sewing machines. The purpose is to allow students touse computerized patterns for sewing.

On the positive side — I have also been in schools that have three or four computer labs, with one set of 4 or 5 computers for teachers to check out for their classrooms. Computers belong in science and math classrooms for students to use in science lab investigations and math problem solving situations.

Computers support the best approaches for teaching science and math — project-based learning investigations, case studies, and problem-based learning situations.


Treating Teachers as Non-Professionals

Teachers are professionals, just like other adults who require a college degree and certification for their career field. This starts in house, where teachers are given the respect they deserve by administrators and central IT gurus, who belief that only they should have the ability to load instructional software on computers. This also means letting teachers have the ability to access online programs and websites that support teaching science and math, without begging for permission.


Anyone who has viewed current science or math textbook understands that most are monumental wastes of money. The need for textbooks is perpetuated by two things – parents who think they are needed and publishing companies that need to make a buck. School systems spend enormous amounts of their budget yearly purchasing textbooks that are out of date the moment they are printed.

Schools typically keep science textbooks for six years or more and scientific knowledge changes every day. Also, these textbooks are overrun with colorful, useless information that only serves to distract and confuse students. Math textbooks are only designed for rote memorization of facts and repetitiously boring math problems.

Just like science textbooks, they are plastered with colorful useless information that only serves to distract and confuse students. Now it is your opportunity to add things you would like to see phased out of science and math education by 2025.
