If `tan6theta=3/4` then `1/2(3c o s e c2theta-4sec2theta)=`

If tan theta=1/sqrt7 ,then (c o s e c^2theta-sec^2theta)/(c o s e c^2theta+sec^2theta)=?

If sintheta=3/4 , prove that sqrt((cos e c^2theta-cot^2theta)/(sec^2theta-1))=(sqrt(7))/3

If theta is an acute angle and t a ntheta=1/(sqrt(7)) , then the value of (cos e c^2theta-sec^2theta)/(cos e c^2theta+sec^2theta) is a. 3//4 b. 1//2 c. 2 d. 5//4

Prove that: ((1+tan^2theta)cottheta)/(c o s e c^2theta)=tantheta

Slove 4tan^2theta = 3sec^2theta

If theta is an acute angle such that sec^2theta=3 , then the value of (tan^2theta-cos e c^2theta)/(tan^2theta+cos e c^2theta) is (a) 4/7 (b) 3/7 (c) 2/7 (d) 1/7

Prove that (1+ tan^4 theta)/(1+ tan^2 theta) = sec ^2 theta-2 sin^2theta

Prove the following : tan^4 theta + tan^2 theta = sec^4 theta -sec^2 theta

If sec^(2)theta+tan^(2)theta=sqrt(3) , then the value of (sec^(4)theta-tan^(4)theta) is

If sec theta + tan theta=(4)/(3) , then sec theta tan theta =_______
