This Maplet serves as a calculator for partial derivatives of functions of two variables. This Maplet was used in a Survey of Calculus and Multivariable Calculus courses. Students can use this Maplet to check their homework or any partial work that requires the computation of partial derivatives. This Maplet uses the power of Maple to compute the partial derivatives of functions that are a bit more complicated functions such as "y* Int(tan(t),t=0..x)".
