Write the value of ` 4 tan^(2)theta-(4)/(cos^(2)theta).`

Write the value of (1+tan^(2)theta)cos^(2)theta.

If tan theta = (3)/(4) , find the value of ((1 - cos^(2) theta)/(1 + cos^(2) theta))

If cos theta=-(1)/(2) and pi

Write the value of sin^(2)theta cos^(2)theta(1+tan^(2)theta)(1+cot^(2)theta).

If sin^(4)theta-cos^(4)theta=k^(4) , then the value of sin^(2)theta-cos^(2)theta is

If (sin theta + cos theta)/(sin theta - cos theta) = (5)/(4) , the value of (tan^(2) theta + 1)/(tan^(2) theta - 1) is

If sin^(2)theta-cos^(2)theta=(1)/(4) , then the value of (sin^(4)theta-cos^(4)theta) is :

If 3cos theta=1, find the value of (6sin^(2)theta+tan^(2)theta)/(4cos theta)

If tan^(4)theta +tan^(2) theta = 2 , then the value of cos^(4)theta +cos^(2)theta is-
