If `tan theta = 5/12 and sin theta` is negative, find `cos theta`.

If tan theta=5/12 then sin theta=

If tan theta = 15/8 and cos theta is negative, find the value of (sin (-theta) - cos theta)/(tan(-theta) + "sec"(-theta)) .

If tantheta=5/12 and and cos theta is negative, find the value of (sintheta+cos(-theta))/(sec(-theta)+tantheta)

Find the quadrant in which theta lies if (i)cos theta is negative but sin theta is positive (ii)sin theta is negative but tan theta is positive (iii) cos theta is negative and sin theta is negative (iv) cos theta and cot theta are both negative (v) sec theta is positive but cosec theta is negative

IF tan theta =12/5 , then cos theta =

If tan theta = a/b then find the simpliest value of (b cos theta-a sin theta)/(b cos theta+ a sin theta)

If tan theta = 1 then find the value of (5 sin theta + 4 cos theta)/(5 sin theta - 4 cos theta)

If tan theta = 4/3 , find the value of (sin theta + cos theta) .

If tan theta = -4/3 , find the value of (sin theta + cos theta) .

If tan theta =12/5 and theta lies in 1st quadrant, then find 5 sin theta-12 cos theta=?
