NUMINT for finding Left Riemann Sums, Right Riemann Sums, Midpoint Riemann Sums, and Trapezoidal Approximations  
SLOPE for calculating the slope of a line after zooming in  
SLOPEFLD for generating slope fields from differential equations. Written by Kent Thele. The program is driven from a main menu.  
SLPFLD for generating slope fields from differential equations  
SlopeFld for the TI84C for generating slope fields on the TI84C (Written by Mason Peterson)  
Trapezoid for generating a trapezoidal approximation for the bounded area under a function. A visual of the function with the trapezoids is not presented.
