Through the use of algebra equations, tables of values of ordered coordinate pairs, and plotting on the Cartesian coordinate plane, students develop a deeper understanding of what it actually means to plot the graph of a function.
The primary function when it comes to graphing calculators is the ability to input a function and have its graph appear in a manner of seconds. There are countless features available to analyze and manipulate the graph. The most commonly used are:. Most application problems you know, those dreaded word problems about trains, planes, projectiles, maximizing revenue, finding the normal force or coefficient of friction in algebra classes can be more easily solved and understood when graphed.
The majority of us are primarily visual learners, and a graphing calculator greatly adds to the learning process. It has to work for you. For the high school student who just got comfortable using a regular scientific calculator last year, it is best to start with a more basic model, such as a TI or TI Both are quite user-friendly, with large easy-to-read buttons and excellent display of numbers, functions, and parentheses or brackets.
It is used to find the value of the angle when you already know the ratio. Many calculators have so many extra functions mapped onto the keys that it can become cluttered, difficult to read, and overwhelming. It is more cost effective and probably better for the learning process, to simply stick with the tried, tested and true models that students have been using for years.
Be sure that the calculator you choose is able to do what you need it to. There are many incredibly powerful things that the latest models of graphing calculators are capable of doing. Some are more tailored towards graphing inputted data for statistics courses, while others are designed with algebra and calculus students in mind.

Once students understand the graph of a parabola and how the a, b, c values affect its shape and intercepts, they usually learn how to use the quadratic formula equation.
It is a tedious and time-consuming process that eventually results in determining the x-intercepts or roots of the quadratic equation. Some students who struggle with arithmetic can complete perhaps 2 or 3 problems in 10 minutes or so. With a quadratic solver app, the roots are solved instantly and we are also offered a graph of the equation, its vertex, maximum or minimum value, and a variety of other characteristics commonly tested in high schools around the world.
Students should of course know how to find the values by hand, and the calculator simply comes in handy as a tool to check answers and confirm understanding.
