`x=cosec^2theta, \ y=sec^2theta, z=1/(1-sin^2thetacos^2theta)` then `xyz` is equal to is equal to

(sec^2theta-1)(cosec^2theta-1)=1

Prove that cosec^2theta+sec^2theta=(sec^2theta)/(sin^2theta)

1/sec^2theta+1/(cosec^(2)theta)=1

(sec^2theta-1)(cosec^2theta-1)

1/sec^2theta+1/(cosec^(2)theta)=

If (sin theta+ cosec theta)^2+(cos theta+sec theta)^2=k+tan^2 theta+cot^2 theta , then the value of k is equal to:

(1-sec^2theta)(1-cosec^2theta) = …………….

cos^(2)theta-sin theta.cos theta-(1)/(2)=0
