" (ii) "quad 2sin^(2)theta-cos theta=1

sin2theta - cos2theta =1

sin^2theta+cos^2theta=1 .

Find the value of theta when 2sin^(2)theta-cos theta=1

The value of theta(0

For any acute angle theta , prove that: (i) sin^(2) theta + cos^(2) theta =1

Prove sin^(2)theta+cos^(2)theta=1

Solve sin^(2) theta-2 cos theta+1/4=0

If "cosec" theta = sqrt(5) , find the value of (i) 2-sin^(2)theta - cos^(2)theta (ii) 2 + (1)/(sin^(2)theta) - (cos^(2)theta)/(sin^(2)theta)

If sqrt(3) tantheta=3sintheta, " prove that " (sin^(2)theta-cos^(2)theta)=(1)/(3).

If sqrt(3) tantheta=3sintheta, " prove that " (sin^(2)theta-cos^(2)theta)=(1)/(3).
