## Ti Nspire CX: Integration of Single and Multivariable Functions – Step by Step

Fortunately, TI Nspire CX users can do Step by Step Integration using Calculus Made Easy at www.TiNspireApps.com . Just enter a function of one or more variables and get the solution immediately. Watch this brief video showing Step by Step Integration:

Just enter a function of one or more variables to find single or multiple integrals – step by step. That involves Integration by parts, U-Substitution, Integration by Partial Fractions, Double and Triple Integrals and Polar Coordinates.

## Partial Derivatives using the TiNspire Cx CAs

Finding Partial Derivatives using the TiNspire can easily be done using Calculus Made Easy at www.tinspireapps.com as follows: In the Menu select Multivariable Calculus, then select Partial Derivatives and Gradient:

Next enter the given function using x and y as variables:

The two partial derivatives are highlighted , the 2. partial derivatives are found shown below.

You do have the option to evaluate the partial derivatives by entering x0 and y0 values in the 2. box as shown below :
