Examples of using

Graphing calculator to find extrema

For example, let’s say we want to determinate the relative extrema of next function:

How to find extrema on Graphing calculator


  1. Input the function into the graphic calculator 
  2. Press Zoom 6 to build a graph 
  3. This looks like a very good window to calculate the relative extrema. If we didn’t have a good view of the graph here we’d had to adjust the window by pressing “Window” button. On this graph, we see a high point – relative maximum and low point – relative minimum. To calculate coordinates of this points press “2nd” button which brings up the calculation menu. 
  4. We have to decide whether we want to find a minimum or maximum first. Let’s find the minimum first by choose option 3.
  5. Now it’s going to ask us a series of questions. The first one is “What is left bound?”. So if we’re trying to find the minimum we need to locate the left side of minimum point and press enter. 
  6. Now it’s ask about right bound, so we need to move the cursor to the right of the relative minimum and press enter again.
  7. Now we see the coordinates of this point. (2, -4) record this. 
  8. Repeat steps 3-7 to find the relative maximum.
  9. Relative maximum is (-2, 4)
  10. That’s it.

Why use a Graphing Calculators (Advantages)

Speedy Math Solving. When you master a skill, it is easier to compute, create, and graph a table of values quickly. They allow students to understand complex mathematical problems by having an easy method of calculating and connecting the problems with real-life activities.

Better Understanding of Concepts. For many students, achieving high-tech skills is a must if you want to gain employment in a demanding company. A graphing calculator helps to lay the foundation for solving problems in a much more realistic way.

How to choose graphing calculator for college // Graphing calculator for college buyer’ guide

Approved by Numerous Educators. These calculators are built with the support of many educators all over the world. They are therefore approved as ideal in achieving the education level and meeting curriculum requirements in schools. That’s why they are permissible for sitting various exams.

Disadvantages of a Graphing Calculator

It may have a Steep Learning Curve. Graphing calculators can be complicated to use for many students in mid school and the first college year. It can take time before you finally understand the menu and user interface when trying to solve problems so you may lag behind if you are using a very advanced graphing calculator.

What does graphing calculator do? Various Uses of it:

For Students. The graphing calculator is an influential piece of technology. For many students, it is vital to reduce the complexity of a math or science problem when solving it to enhance understanding of a concept.

For Algebra. If you are trying to multiply or factor algebraic expressions, a graphing calculator will help you to use several approaches to solve that problem.

For example: Calculate y= 2x+1

The algebra calculator will help you graph the equation as:How to choose graphing calculator for college // Graphing calculator for college buyer’ guide

How to find the minimum and maximum values using the TI-84 Plus CE Graphic Calculator, look at the video:

Find Minimums & Maximums With the TI-84 Plus CE Graphing Calculator

For Trigonometry. Make short use of a graphing calculator to solve complex trigonometric equations.

For example, solve Cos 2x=2Cos x.

You’ll just need to graph the two functions as y1=Cos 2x and y2=2Cos x.How to choose graphing calculator for college // Graphing calculator for college buyer’ guide

y=Cos 2x and y= 2Cos x where the intersections will help you solve for x.

For Physics. Analyzing data in Physics experiments is also easy with a graphing calculator. It is used to calculate the maximum value of a parabola in an investigation like the bouncing ball shown in this graph.How to choose graphing calculator for college // Graphing calculator for college buyer’ guide

Placement Tests. First-time users of the graphing calculator are advised to buy a calculator with an exact/appropriate mode. This gives you accurate answers instead of an estimate of the solution like in decimals.

Placement tests usually test for elementary to college-level geometry, algebra, and trigonometry. A graphing calculator at this stage is only used to check your work since you will be required to show your work by hand.

Tax Refund Students

If you are learning how to prepare tax returns, the graphing calculator provides modes for inputting figures and numbers for tax computation, depreciation methods, calculating bad debts, and many other calculations surrounding taxes.


You can use your graphing calculator to determine a teacher’s salary and how much goes into federal payments, Medicare, Taxes, and social security. Teachers can also calculate how students spend their hours and present the information in a graph to assist students to manage their time properly.


As an investor, you can use a graphing calculator to solve a certain parameter of a particular investment plan. You can calculate the return rate needed to reach a certain amount like your kid’s college fund. These calculators can have a return rate tab to help with the calculation of CDs, Bonds, Stocks, and many others.

Which Calculators are not accepted in College?

Calculators that are not accepted in College:

  • Every college has a calculator policy, but most rules apply across many colleges.
  • Calculators that are not battery-operated
  • Cell phones, laptops, tablets, smartphones, and computer calculators
  • Calculators with a computer-like keypad or use a stylus for input
  • Calculators that have a paper print or make noise during use
  • Some touchscreen calculators are also not acceptable

Features to Expect in a Graphing Calculator

Table and Points. They allow you to view tables and points so that you can trace a graph when solving a problem

Factorial, piecewise Functions, and Trigonometric Functions. These are calculators that support operations like sin (x), cos (x), tan (x), etc. and factorial solving. It is usually the exclamation mark (!) which represents a much more complicated math solving identity.

Graphing calculators will allow you to explore piecewise functions such as:How to choose graphing calculator for college // Graphing calculator for college buyer’ guide

Coordinates, Imaginary numbers, Matrix. Arriving at an answer can be in many ways when using a graphing calculator. They offer methods of solving equations using coordinate points by giving you a plane with the x and y-axis. A point in a complex plane is in the form (a+bi) where a represents real numbers and b the complex part of the equation.

You can then follow through by plotting real numbers on the x-axis, and imaginary numbers on the y-axis like you would plot (x,y). Now, you will have the coordinate points to solve that particular equation.

The matrix function allows input of matrices when solving problems involving a system of equations.

Graphing Calculator vs. Phone App

Graphing calculators are handheld devices designed specifically for mathematics and science. Mobile phone calculator apps take the same system that you see on the handheld calculator and create a program for it so that it can be used on the phone.

Graphing calculators are fully developed, and you can use them in classes and exam rooms while phone calculators are mostly in the development stage; so they are not allowed in exams.

Having a graphing a calculator as an app can be good if you can stay away from the need to text, play games, and more. But we are far from seeing these calculators allowed in the classroom setting.


Finding the right calculator for college depends on the features you need for that specific model. There are many capabilities on a graphing calculator from those that use Computer Algebra Systems (CAS) to non-CAS versions which help in solving basic math problems.

We hope we have covered the best calculators for college students. These are models that solve scientific and mathematical problems both in the classroom and exam room. The advanced features will help you understand problems so that you can perform better and advance your career.

We believe you’ll get the most out of these graphing calculators.
