Density and Contour Plots (Mathematica Tutorial)

Density and contour plots. This gives a density plot of sin(x) sin(y). Lighter regions show higher values of the function. Some options for DensityPlot.

IVPs with Piecewise Coefficients (Mathematica Tutorial)

The differential equations that arise in modern applications often have discontinuous coefficients. DSolve can handle a wide variety of such ODEs with piecewise coefficients. ...
