Mathematics for Computer Science - Lecture Notes
This is useful, but pretty standard undergrad material. There are more interesting OCW courses, such as Street Fighting Mathematics:This course teaches the art of guessing results and solving problems without doing a proof or an exact calculation. Techniques include extreme-cases reasoning, dimensional analysis, successive approximation, discretization, generalization, and pictorial analysis. Applications include mental calculation, solid geometry, musical intervals, logarithms, integration, infinite series, solitaire, and differential equations. (No epsilons or deltas are harmed by taking this course.)http://ocw.mit.edu/courses/mathematics/18-098-street-fightin...
