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

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

If sin theta = cos theta , " then " 2 tan^(2) theta + sin^(2) theta -1 is equal to .............

If sin theta+cos theta=1, then the value of sin2 theta is equal to

If sin theta+cos theta=1 then the value of sin 2 theta is equal to

Ifcos 2 theta+9sin2 theta+6sin theta+54cos theta=1 then the value of 100tan^(2)theta+9tan theta is equal to

If theta is an acute angle and sin theta=cos theta, find the value of 2tan^(2)theta+sin^(2)theta-1

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

The value of sin^(2)theta+(1)/(1+tan^(2)theta) is equal to
