Asked by | 22 Jul, 2012, 10:04: PM
Expert Answer
cos theta+ sin theta / cos theta- sin theta
Divide the numerator and denominator by cos theta to get,
1+ tan theta / 1 - tan theta ... (1)
From the given relation,
3 sin theta = 4 cos theta
tan theta = 4/ 3
Put this value in (1) to get the required answer.
