How to Find the Derivative of a Function Using a TI-84 Plus CE

Finding the derivative of a function is a crucial part of calculus. The derivative of a function measures the rate of change at a given point. This can be used to find important information about the function such as its maximum or minimum values, its turning points, or even its increasing and decreasing intervals. This guide will explain how to find the derivative of a function using a TI-84 Plus CE calculator.

Before we start, make sure that your calculator is in the correct mode. The mode can be set by pressing the Mode button and selecting the Func option. Once the mode is set, you are ready to find the derivative of a function.

To begin, enter the function that you want to find the derivative of. This can be done by pressing the Y= button and entering the function. After you have entered the function, press the 2nd button and then the CALC button. This will bring up a menu of different operations that can be performed on the function.

From this menu, select 1:dy/dx. This will calculate the derivative of the function that you entered. The result will be displayed on the screen.

It is also possible to find the derivatives of multiple functions at once. To do this, enter each function that you want to find the derivative of into the Y= menu. After this, press the 2nd button and then the CALC button. This will bring up the same menu as before.

From this menu, select 2:dy/dx(n). This will calculate the derivative of each function that you entered. The results will be displayed on the screen.

Finally, it is possible to find the integral of a function. To do this, enter the function into the Y= menu. After this, press the 2nd button and then the CALC button. This will bring up the same menu as before.

From this menu, select 3:Int(dx/dy). This will calculate the integral of the function that you entered. The result will be displayed on the screen.

Finding the derivative of a function using a TI-84 Plus CE calculator is a relatively simple process. With just a few steps, you can easily find the derivative of a function, multiple functions, or even the integral of a function. This guide has outlined the steps that you need to take to find the derivative of a function using a TI-84 Plus CE calculator. Now, you are ready to start finding the derivatives of your own functions
