TI-82 Graphing Calculator – Old but Still A Reliable Calculator

ti83 review

The TI-82 graphing calculator from Texas Instruments contains tables, data modeling and many other great features. Its interface is simple to understand and easy to use. As such, it’s an excellent choice for new users who don’t have much experience with advanced calculators.

Useful features

The commands are all grouped in a way that makes sense and are very easy to access. The menus aren’t layered in a complex way as they are on many other graphic calculators. One problem that more experienced users may find is that the TI-82 graphic calculator doesn’t have string and conversion capabilities. This may not be a big issue for some users—that is, if they don’t need to convert from one unit to another.

It does, however, have plenty of advanced features that will come in handy for any type of user such as graphing abilities, advanced equation solving and statistical analysis capabilities. The TI-82 has all the features anybody could ask for when it comes to graphing and solving mathematical problems. If this old but gold calculator isn’t enough for your needs, try to read this top graphing calculator article.

great calculator for math

Here are some of the reasons why you should consider getting the TI-82 graphing calculator:

  • It contains an eight-line x 16 character display.
  • You will be able to store up to 10 functions.
  • Up to 10 functions can be graphed simultaneously.It has constant memory.
  • It’s programmable.
  • It can compute roots, integrals, derivatives and values of a function.
  • Graphical zoom features.
  • It has up to 14 digit accuracy.
  • The high screen is 94 pixels wide by 82 pixels high.
  • It can display tables of functions, showing both inputs and outputs.
  • It can handle matrix operations.
  • Its screen can be projected onto an overhead.It has the ability to work with histograms, regression equations and scatter diagrams.

One great thing about the TI-82 is that it only takes AA batteries. Users won’t have to worry about going through a lot of trouble getting the batteries replaced, as they can do it themselves. This calculator also has 28.2 K bytes of memory, giving students a lot of room in which to store formulas and equations. The memory maybe not enough for some users, if that is the case I suggest get the TI-84 Plus CE, read the review here.

It’s also one very amazing calculator in terms of input and output lists. Students who normally struggle in math and/or science classes will find that TI-82 calculators will make things a lot easier for them. This impressive device will allow for students to create 3D graphs and derive plot points all at the push of a couple of buttons.

Teachers will usually take the time to help students use advanced calculators to solve math problems.  There are also instruction guides available for download on the internet. TI-82 calculators are very affordable. New and used ones both can be ordered online or on amazon for less! They are ideal for inexperienced users, although advanced users will gain a lot from using them as well.

Baby Jogger City Elite Single Stroller Review



If you seek an all-terrain stroller, the Baby Jogger City Elite Single Stroller provides an easy and comfortable commute with exceptional features to make day trips a breeze. Despite the company name, this particular stroller isn’t designed for actual jogging.


The wheel system

Since the wheels are inflated with foam instead of air, it creates a lightweight system that is also durable and shock-resistant.

The 12-inch forever air swivel wheels with sealed ball bearings are great for any daily obstacle you may encounter out with your child and provides a smooth and comfortable ride.

The wheels easily lock into place for straight, long distance strolling. Located on the adjustable handlebars is a hand-operated brake for ease in sudden stops.

The frame

If you are running errands all day with your children, you don’t want to constantly remove a heavy, bulky stroller from your trunk. Baby Jogger has produced a lightweight aluminum frame that makes transport and storage a breeze. Though the frame is light, it doesn’t sacrifice in durability and it is designed for lasting use.

With the simple lift of a strap, the whole stroller folds itself for easy and convenient transport. The auto-lock secures the stroller in place in its closed position.


The seat

For extended periods of time in the stroller, you definitely want a comfortable seat. This Baby Jogger stroller contains a seat that reclines to a near flat position and provides ventilation for more air circulation throughout the stroller on particularly hot days.

In addition, there is a raised kicker for added leg support for smaller children as well. The stroller contains an SPF 50+ adjustable sun canopy with a retractable weather cover to protect against inclement weather. To further increase circulation, there are side ventilation panels that are secured with magnets.

You are able to check on your child inside the stroller through the peek-a-boo windows located at the top of the canopy. Connected to the stroller is a built-in parent console that holds all of your personal belongings, such as a cell phone or wallet.

In addition a seat-back pocket, there is vast undercarriage storage for extra clothing, food, and other essentials for a long day away from home.


The City Elite Single stroller instantly becomes a travel system with the addition of a car seat. There are several adapters available to fit your particular car seat system. For even the smallest baby, there are prams/bassinets that fit to the stroller as well.

There are numerous other accessories that fit to the stroller, including the useful snack tray and liquid holder, and cold weather additions like the foot muff.


The Baby Jogger Elite is perfect for a sunny day and protects your child from all of the elements. This lightweight design still manages to provide all of the essential features for a practical, durable and useful stroller that could be further customized for the needs of you and your family.

Rational Functions and Other Essential Functions

Part two of the Essential Functions series examines power, trigonometric and rational functions. Power functions have the form of x^a, where a can be any real number. This part of the video series examines cases 2 (a between 0 and 1) and case 3 (a less than 0). The first case is examined in part 1.

The power functions are graphed for each case to visualise the power relationship. Case 3 functions will create infinite discontinuities (asymptotes). Rational functions are formed by the division of two polynomial functions; P(x) and Q(x). Infinite discontinuities will occur wherever Q(x)=0.

This is because any number divided by 0 is essentially infinite. Vertical asymptotes will form wherever the bottom of the function is nothing. The number of discontinuities depends on the order of Q(x). Trigonometric functions have been studied in algebra but will be needed for future calculus studies.

Sine, cosine, and tangent functions are periodic. Sin(x) and Cos(x) have a period of 2*pi whereas tan(x) has a period of pi. Sin(x) looks like a shifted version of Cos(x), they are essentially the same but are 90 degrees out of phase. The range of sine and cosine is between -1 and 1. The range of the tangent function is the whole real number set. The trigonometric functions are graphed so that they can be visualized and memorized. Until next lessons guys!
