2(cos^(2)theta in sin^(2)theta)=1

Find the general value of theta from the following equations :2(cos^(2)theta-sin^(2)theta)=1

2(cos^(2)theta-sin^(2)theta)=1(theta is a positive acute angle),then cot theta is equal to

If 2(cos^(2)theta-sin^(2)theta)=1,theta is a positive acute angle , then the value of theta is

Evaluate 2(cos^2theta-sin^2theta)=1

Prove each of the following identities : (i) (1- tan^(2) theta)/(1+ tan^(2) theta) = ( cos^(2) theta - sin^(2) theta) (ii) (1- tan^(2) theta)/(cot^(2) -1) = tan^(2) theta

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

If 2cos^(2)theta-2sin^(2)theta=1, then theta equals to

Complete the following activity by filling the boxes. sin^(2) theta+cos^(2) =square ….(Identity) Dividing each term by sin^(2) theta , we get (sin^(2)theta)/(sin^(2) theta)+(cos^(2)theta)/(sin^(2)theta)=(square)/(sin^(2)theta) :.1+square=square

If cos theta+cos^(2)theta=1 then sin^(2)theta+2sin^(2)theta+sin^(2)theta=
