Step 1

We know that any point on the circle of radius r corresponds to t is ( rcost, rsint). Here r=1. Therefore, any point on unit circle corresponds t is (cost, sint), Substituting t=1 and comparing with the given point , we get required value of sine and cosine.

Step 2

Now, by dividing the value of sine by the value of cosi...
