If `sin theta=(x^2-y^2)/(x^2+y^2)` then find the values of `cos theta` and `cot theta`

If cos theta = (2x)/(1+x^2) , find the values of sin theta and cot theta [Given x^2 lt 1 ]

If cot theta = (x)/(y) , find the value of: " " ( x cos theta + y sin theta)/( y sin theta - x cos theta)

if tan theta=(x)/(y) then sin2 theta+cos2 theta is

If x sin^3 theta+ y cos^3 theta = sin theta cos theta and x sin theta = y cos theta, Find the value of x^2 + y^2.

If x sin ^3 theta +y cos^3 theta = sin theta cos theta and x sin theta =y cos theta then x^2 +y^2 is

If x sin^(3) theta + y cos^(3) theta = sin theta cos theta ne 0 and x sin theta - y cos theta = 0 , then value of (x^(2) + y^(2)) is :

If x sin^(3) theta + y cos^(3) theta = sin theta cos theta and x sin theta = y cos theta , then the value of x^(2) + y^(2) is :

If 3cot theta=4, find the value of (4cos theta-sin theta)/(2cos theta+sin theta)

If x sin^(3)theta+y cos^(3)theta=sin theta cos theta and x sin theta=y cos theta Find the value of x^(2)+y^(2)
