Can you transform sine functions into cosine functions?

Answer:
If you know the measure of one angle, and the length of one side of a triangle, you can find the measures of the other sides and angles. From there, you can find the values of the other trig functions.

cos (x) = sin (90-x) in degrees
there are other identities such as cos^2+sin^2=1, so cos^2=1-sin^2
