# Rectangular and Trapezoidal Approximations

This applet allows for visualization of rectangular and trapezoidal approximations of areas under curves.
R is the value of the rectangular approximation
T is the value of the trapezoidal approximation
a is the left endpoint
b is the right endpoint
n is the number of rectangles
d is the position of the right of the rectangle (it can shift from a left endpoint to midpoint to right endpoint approximations)
