sine graph will be formed at origine of graph and cosine graph is find on y-axise
The anti derivative of negative sine is cosine.
the only close answer i know is: eix = cos(x)+i*sin(x) where i is imaginary unit
Generally, the derivative of sine is cosine.
Period is how long it takes for the sine and cosine functions to restart repeating themselves. Both have a period of 2pi (360 degrees).
