Calculator Project

This calculator will walk you through approximating the area using Trapezoidal Rule.

Please enter a function, starting point, ending point, and how many divisions with which you want to use Trapezoidal Rule to evaluate.

Note: Trigonometric functions are evaluated in Radian Mode. Please convert degrees to radians.
Also, if your bounds contain symbols (i.e. pi/2, sqrt(2), etc) . Plug in the numerical representation (i.e pi/2 = 1.57079632679)
