(iii) ( 1 + tan^2 theta ) ( 1 + sin theta ) ( 1 - sin theta ) =1
prove that cos^2theta(1 + tan^2 theta) = 1
If u_(n) = sin ^(n) theta + cos ^(n) theta, then 2 u_(6) -3 u_(4) is equal to.......... A) -1 B) 12 sin ^(2) theta cos ^(2) theta C) 1 D) 12 tan ^(2) theta cos ^(2) theta
1+tan^(@)theta =?
If cot theta = (7)/(8) , then tan^(2) theta =
cos 2 theta is not equal to ................... A) 2 cos ^(2) theta -1 B) 1- 2 sin ^(2) theta C) (1+ tan ^(2) theta)/( 1- tan ^(2) theta) D) (1- tan ^(2) theta)/(1+ tan ^(2) theta)
Prove the following : tan^4 theta + tan^2 theta = sec^4 theta -sec^2 theta
If tan theta + 1/ tan theta = 2, then show that tan^2 theta + 1/tan^2 theta= 2 .
prove that If tan theta + (1)/ (tan theta) = 2 then show that prove tan^2 theta + (1) / (tan^2 theta)
