# Tinspire CX CAS : Potential Function and Conservative Vector Field – Step by Step

To Find the Potential Function for a given Vector Field such as the one at http://tutorial.math.lamar.edu/Solutions/CalcIII/ConservativeVectorField/Prob4.aspx use the Vector Calculus Made Easy app at https://www.tinspireapps.com/?a=VCME , go to option 3,4 and enter the Vector Field as: Since the 2 partial derivatives match the Vector Field is conservative and the Potential Function is found as shown below:
