Overview: This example allows you to evaluate equations using Eval Formula Node.vi (Mathematics>>Scripts & Formulas>>1D & 2D Evaluation).  This is similar to the Formula Node but with variables and formulas that can be entered on the front panel.

Description: In this particular VI, we are calculating the diameter, area, and circumference of a circle when given the radius and value of pi as inputs.  This example shows how to enter simple equations in a string control and how to setup the input variables, input values, and output variables as well.

Requirements: LabVIEW 2012 (or compatible). Hardware: none.

Steps to Implement or Execute Code: Insert values interested in, run the VI, write down the results.
