Ti-Nspire is a graphing calculator that has diverse functions, people can use Ti-Nspire to Graphing Functions, Solving functions, and you can even use it to play games.
Back to Home PagePress [CTRL] [I], and select Add Graphs →Add Graphs to insert a new Graphs page into a current document1. By default, your new Graphs page opens with a coordinate graph displayed on the screen1.
Notice the blinking cursor located on the entry line, the narrow space located at the bottom of the screen1. The entry line is used to type functions1, and you can Start typing the equation. After typing the equation, press [ENTER] to activate the graph1.
If you cannot see all of the graph that you might want to see, you can adjust the window setting, after you have graph a graph, press menu, press 4(Window/Zoom), and press 1(Window Settings), Set the Xmin/max and Ymin/max to change the range and domain that the calculator will show.
The solve function can help you find out the zeros of your function. Open your calculator or go to the main page, and press A(Calculate) go to calculate page. Firstly, type in solve(), in the bracket, type in your function (For example, solve(3x-5=0) if you want to find the roots of the function, type x (with comma at front) after the function tou type (for example, solve(3x-5=0,x)), then, you can press enter and the calculator will find out the roots (the answer of the example will be 5/3).
The factor function can help you find out a factor of your function. At the same page, you can type in factor(your function) and press enter, the calculator will help you find out the factor of the function you type in (for example, factor((x^2)-5x-36), the answer will be (x-9)(x+4)).
The Expand work as the opposite of the factor function, it can help you to expand a function you type (for example, expand((x-9)(x+4)), the answer will be (x^2)-5x-36)).
