Title: Trigonometric function: Sine and Cosine
Post by: Fu-Kwun Hwang on February 18, 2008, 08:38:14 pm
This simulation shows relation between sine/cosine function with tow vectors.
The black vector is a unit vector (with length 1), red arrow represents the cosine function while green arrow represent the sine function.
You can drag both arrows to find out how sine/cosine changes with angle between arrows.
