Showcase - 2011 MERLOT Classics Award - Exploring Multivariable Calculus

Exploring Multivariable Calculus is an excellent tool which a student can use to visualize surfaces in 3D. A student can enter up to four equations where some of them can be in another coordinate system such as cylindrical or spherical or even implicit. The graphs are rendered in an easy to visualize manner. The wide variety of menu options allows a student to grab and turn the graphs until they are easy to visualize.
