Concepts covered in this course include: standard functions and their graphs, limits, continuity, tangents, derivatives, the definite integral, and the fundamental theorem of calculus. Formulas for ...

Mathematicians once turned up their noses at imaginary numbers. But complex analysis actually simplifies math and physics.

So Weierstrass rewrote them, using precise language and concrete mathematical formulas. (Every calculus student learns the epsilon-delta definition of a limit; it was Weierstrass who introduced ...
