Description

Definite integral of the product of cosines. The integral of cos(mt) * cos(nt) = 0, except for the special case when m = n. When m = n, the integral evaluates to pi.

Electrical engineering

Learn about electricity, circuit theory, and introductory electronics. We also have sections that let you get down and dirty with household items, from building your own robot to videos where we disassemble household items to see what's inside.

Fourier series

The Fourier Series is a way to approximate any arbitrary periodic signal as the sum of sines and cosines.

Topic: Science

Learn about all the sciences, from physics, chemistry and biology, to cosmology and astronomy, across hundreds of videos, articles…
