If We Start at the Point (1, 0)and Travel Once

Short Answer

If we start at the point (1, 0)and travel once around the unit circle, we travel a distance of 2 π  units and arrive back where we started at the point (1, 0). If we continue around the unit circle a second time, we will repeat all the values of x and y that occurred during our first trip around. Use this discussion to evaluate the expression.
