If `cos theta = t(0lt t lt 1) and theta ` does not lies in the first quadrent , find ` sin theta and tan theta `.

If sin theta = k , 0 lt k lt 1 and ' theta ' does not lie in the first quadrant , then tan theta =

Find theta if sin theta -cos theta lt0

If (cos theta)/(1- sin theta) + (cos theta)/(1 + sin theta) =4 , then find the value of cos theta . Find theta if 0^(@) lt theta lt 90^(@)

If 0 lt theta lt pi/2 and sin 2 theta = cos 3 theta, then the value of sin theta is-

If sin theta + cos theta=0 and 0 lt theta lt pi , then theta=

If : 0 lt theta lt pi/2 and sin 7theta + sin 4 theta + sin theta=0 , then : theta =

If sin theta = sqrt(3) cos theta, 0 lt theta lt 90^(@) , then theta is equal to .
