Question 395071: Please help me solve this problem:
Suppose that cot (Beta)= 9/7 and Beta is not in Quadrant I. Find sin(Beta) and cos(Beta). Use fundamental identities, give exact answers and rationalize if necessary.
Thank you!

We have

. This number is positive, so either sine and cosine are both positive or both negative, so the angle is in quadrant III (since it's not in quadrant I).

Hence, and for some negative number x that we wish to find. By the Pythagorean identity,

--> and .
