This VI illustrates a quadratic function in standard form, *f(x)=ax^2 +bx +c. The VI graphs the function, finds the vertex, writes the function in vertex form, finds the discriminant of the function, and finds the zeroes of the function.

Riemann Sum

Calculus

Riemann Sum readme.pdf

This VI calculates the definite integral of a function. Additionally it calculates and displays two approximations of the integral by finding sums of the areas of two sets of rectangles-a Left Hand Sum and a Right Hand Sum.
Controls for the beginning and end values of the interval for integration are included. The interval from Start to End is divided into subintervals, delta x in length. Each subinterval determines a rectangle where the height of the rectangle is the value of the function at the right or left endpoint of the subinterval.
