" If "sqrt(3)tan theta=1," value of "sin^(2)theta-cos^(2)theta" is."

If sqrt(3)tan theta=1 then find value of sin^(2)theta-cos^(2)theta

If sqrt(3) tan theta=3 sin theta and theta!=0 then find the value of sin^(2)theta-cos^(2)theta .

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

If sqrt3 tan theta = 3 sin theta , find the value of sin theta^2 theta - cos^2 theta , where theta ne 0 .

If tan(theta + 3theta) tan (2theta + 3theta)=1 , then the value of sin(5theta - 2theta) is:

If sin theta = cos theta ,then the value of 2 tan^(2) theta + sin^(2) theta -1 is equal to

If sqrt(3)sin theta=cos theta, find the value of (3cos^(2)theta+2cos theta)/(3cos theta+2)

If sin theta = cos theta find the value of : 3 tan ^(2) theta+ 2 sin ^(2) theta -1

If tan theta = (1)/( sqrt(3)) , prove that 7 sin^(2) theta + 3 cos ^(2) theta = 4

If sqrt(3) "tan" theta = 1 "and " theta is acute find the value of sin 3theta "cos" 2theta .
