Some topics in math are best learned by rote. This is a worksheet that covers one topic - the product rule in differential Calculus - and contains *65* questions that very in difficulty, with *complete solutions*. This is a terrific resource for students who will be tested on performing the algorithm of differentiating a product of two functions. There are enough questions here that they can do as many as they need to in order to get the process down.
This is also a great tool for teachers. Going into a class and need some good examples to go over? Just pull out this sheet, rather than trying to make one up on the spot. Also great to give to TAs to do the same with students in lab scenarios.
If anything with this sheet is not exactly as you would like, just let me know, and I'll do what I can to meet your need. Enjoy!
