`sin theta = cos theta`. Find `theta`.

If 2sin theta=2-cos theta find sin theta

If sin theta=cos theta then find theta ?

sin theta+cos theta=1 Find (sin theta-cos theta)^(2)

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

Prove each of the following identities : (i) (sin theta - cos theta)/(sin theta + cos theta) + ( sin theta+ cos theta)/(sin theta - cos theta) = (2)/((2 sin^(2) theta -1)) (ii) (sin theta + cos theta ) /(sin theta - cos theta) + ( sin theta - cos theta) /(sin theta + cos theta) = (2) /((1- 2 cos^(2) theta))

Evaluate : sin theta cos theta - (sin theta cos (90^(@) - theta) cos theta)/( sec (90^(@) - theta)) - (cos theta sin (90^(@) - theta) sin theta)/( cosec (90^(@) - theta))

If sqrt(3)sin theta=cos theta, find the value of (sin theta tan theta(1+cot theta))/(sin theta+cos theta)

If 5 tan theta =4 then find the value of (5 sin theta - cos theta)/(sin theta + 3 cos theta)

If (sin theta + cos theta)/(sin theta - cos theta)=3 , then the value of sin^(4)theta - cos^(4)theta is:

(1 + cos theta + sin theta) / (1 + cos theta-sin theta) = (1 + sin theta) / (cos theta)
