How To Use A Graphing Calculator?

Investing in a graphing calculator is essential for any student who wishes to excel at pre-calculus. Since the advent of graphing calculators, maths courses have evolved and become more versatile. A graphing calculator offers countless advantages. Even if your instructor won’t allow you to utilize one on a test, it is always an indispensable tool for verifying the accuracy of homework problems.

With an array of graphing calculators on the market, each has unique inner mechanics. If you’re trying to decide which pre-calculus textbook to buy, consult someone who has already taken the course and then search online for the best price.


A hint: Investing in a calculator with an exact/approximate mode can be beneficial compared to decimal approximations, as it will provide precise measurements that teachers commonly seek.

Even if you’re permitted to use a graphing calculator, it’s still best to complete your work manually. Afterward, verify that everything is correct with your graphing calculator. In this manner, you won’t become reliant on technology to complete tasks for you; eventually, there may be times when using a calculator or other device is restricted (such as during college maths placement tests). It is wise to understand how to solve a problem manually so that you can validate that the solution your calculator gave was, in fact, correct. The result will be erroneous if you mistakenly enter incorrect digits into a calculator. With a thorough understanding of pre-calculus fundamentals, you can quickly pinpoint mistakes!


Utilizing a graphing calculator can cause you to miss fundamental theoretical ideas within pre-calculus. Equip yourself with knowledge before using a graphing calculator – even if you can. If your ambition is to advance in calculus classes, grasping the fundamentals and principles behind each lesson is critical.

Here are some fantastic pointers to assist you in utilizing your graphing calculator:

  • To ensure accurate calculations, always verify that the mode on your calculator matches the maths problem you are solving. Search for a mode button on the calculator, and you’ll be ready! Depending on your calculator type, pressing this button can make modifications such as degrees to radians or f(x) to r(i). For example, your calculator must be aware if you’re solving a problem regarding degrees. The same goes for working with radians! Some calculators offer more than ten different modes; however, be sure to stay calm and choose wisely!

  • Before plotting a graph, ensure that you can solve for y. Your graphing calculator will only accept equations that have been solved in terms of y, and as long as this is done, virtually anything can be illustrated on your device.
  • Utilise all of the shortcut menus at your disposal, and take advantage of each feature the calculator offers to get the most out of it. Graphing calculators are packed with shortcuts to help you quickly and easily understand other mathematical concepts like converting decimals into fractions, finding roots of numbers, or entering matrices for operations. Each calculator is different, so remember to read the manual! These fun tools provide various ways to verify your work, making them invaluable!

  • Enter an expression verbatim, and the calculator will take care of the rest – simplifying it for you. With a graphing calculator, you don’t need to worry about getting the order of operations right. Some built-in maths shortcuts even start with grouping parentheses so that all you have to do is input your data and get an answer in no time!

To illustrate, a calculator may initiate the square root function as

Consequently, any data entered after the parentheses are immediately surrounded by square root symbols until closed. For example,

An intelligent calculator can quickly answer two separate calculations, yielding two disparate results (3 and 7). Soon enough, you may not need pre-calculus classes; the calculator will do all the work!

Wrapping Up……

Graphing Calculators Improve Student Learning: From research, we know that when effective teaching with graphing calculators is employed, students gain a better understanding of mathematical principles, increase their problem-solving abilities and achieve improved performance measures. For those wishing to venture into accounting, finance, or related fields, the ability to evaluate mathematical problems and play with numbers is a significant advantage. This can be especially helpful for students studying towards qualifications such as Chartered Accountancy (CA) and Cost & Management Accounting (CMA). With the appropriate skillset, success in these areas of expertise can become much more achievable.

Frequently Asked Questions (FAQS)

Here are some users’ most frequent inquiries about using graphing calculators effectively.

Q. Are Graphing Calculators Still Helpful?

Ans. Graphing calculators are indispensable for high school (and even collegiate) success. Not only do students need them to effectively understand maths concepts like Algebra, Geometry, and Calculus, but they’re also essential components of standardized testing preparation.

Q. What Is A Graphing Calculator, And How Are They Used?

Ans. For complex equations, a graphing calculator is an invaluable tool. Not only does it display plotted graphs for results such as parabolas and other shapes, but it can also handle numerous equations simultaneously and conduct vastly more complex computations than standard calculators.

Q. What is the Difference Between Graphing and a Scientific Calculator?

Ans. Scientific calculators are invaluable to students studying algebra, engineering, and statistics. Graphing calculators take it one step further by featuring a high-resolution screen that allows users to plot coordinates and graph functions for even more accurate calculations.

Q. Why Is A Graphing Calculator Needed?

Ans. With the power of these innovative devices, you can do much more than just basic calculations. They are able to graph equations, construct function tables and solve equations, and also have the capacity to conduct statistical analysis and calculus work!

Q. What Age Do You Need A Graphing Calculator?

Ans. While tablets and phones may have some of the arithmetic features that maths students require, many high schoolers don’t start using them until their upper grades. However, for those who wish to excel in advanced mathematics, becoming familiar with this device is essential –especially since its use isn’t typically allowed during tests.
