sin^(6)theta+cos^(6)theta+3sin^(2)theta cos^(2)theta=1

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

Prove the following identity: ((1)/(sec^(2)theta-cos^(2)theta)+(1)/(cos ec^(2)theta-sin^(2)theta))sin^(2)theta cos^(2)theta=(1-sin^(2)theta cos^(2)theta)/(2+sin^(2)cos^(2)theta)

Prove the following identities: 2(sin^(6)theta+cos^(6)theta)-3(sin^(4)theta+cos^(4)theta)+1=0sin^(6)theta+cos^(6)theta+3sin^(2)theta cos^(2)theta=1(sin^(8)theta-cos^(8)theta)=(sin^(2)theta-cos^(2)theta)(1-2sin^(2)theta cos^(2)theta)

If sin^(2)theta cos^(2)theta(1+tan^(2)theta)(1+cot^(2)theta)=lambda then find the value of lambda.

If l cos^2 theta + m sin^2 theta =(cos^2 theta (cosec^2theta +1))/(cosec^2 theta -1), 0^@ lt theta lt 90^@ , then tan theta is equal to

sin^2theta+cos^2theta= (a) 0 (b) -1 (c) 1 (d) 2

If |[1+sin^2theta, cos^2 theta,4sin 2theta] , [sin^2theta, 1+cos^2theta,4sin2theta] , [sin^2theta,cos^2theta,4sin2theta-1]|=0 and 0 lt theta lt pi/2 then cos4theta=

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

If : sin^(4)theta+cos^(4)theta+sin^(2)theta*cos^(2)theta=1-u^(2), "then" : u=
