There, Madhava (c 1340-1425) developed series expansions for trigonometric functions. He derived an infinite series combining the reciprocals of the odd numbers and converging to pi.

The goal of this module is the help students better understand the trigonometry and inverse trigonometry functions, law of sines, and law of cosines. The application will generate a triangle with a ...

Two New Orleans high school students have proven the Pythagorean Theorem using trigonometry without relying on circular reasoning. That should be impossible.

"We're going to look at trigonometry in a new way," says Wildberger. "We're going to leave sines and cosines to the circular motion part of mathematics and not force it on triangles." ...

Integration is the inverse of differentiation of algebraic and trigonometric expressions involving brackets and powers. This can solve differential equations and evaluate definite integrals.
