Suppose A is the arc on the unit circle that connects (1,0)(1,0) to (-12/13, 5/13)(−1213,513) and passes through (0,-1)(0,−1). Let uu be the measure of the angle that subtends this arc. Find the value of sin(u)sin(u)?
1 Answer
See below.
Explanation:
If we pass through point
We can see by the coordinates
I have given the angle as a negative rotation, but in angles subtended by arcs this is usually given as a positive angle .i.e.
