If cos theta- sin theta =0 and theta lies in the first quadrant then find the values of theta
~~~~~~~~~~~~~~~~~~~~~~~ 

cos%28theta%29+-+sin%28theta%29 = 0  ----->  cos%28theta%29 = sin%28theta%29  ---->  (divide both sides by cos%28theta%29)  ---->  tan%28theta%29 = 1  ---->  theta = pi%2F4.


Answer.  theta = pi%2F4.
