Use the fact that the period of cosine and sine functions is 2π or 360 degrees to find the cosine and sine of 1,110 degrees.

anonymous · Answer

Just subtract 360 multiple times until you are left with a degree measure of less than 360 degrees.

When you find that measure of less than 360 degrees, you should be able to find the values for cosine and sine.
