Electrical engineering: Sine and cosine from rotating vector
Beschrijving
One way to generate sine and cosine is to track the motion of a rotating vector. Animated.
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.
AC circuit analyisis
If we limit ourselves to input signals shaped like sines or cosines, we can develop a whole AC analysis method to figure out what happens in circuits with changing signals. The methods are far simpler than solving a differential equation.
Topic: Science
Learn about all the sciences, from physics, chemistry and biology,…
