[" If "(1-tan^(2)theta)/(sec^(2)theta)=(1)/(2)," then the general "],[" value of "theta" is "]

If (1-tan^2theta)/(sec^2theta)=1/2 then the general value of theta is

If: tan^(2) theta + sec 2theta =1 , then the general value of theta is

If sqrt(2)sec theta+tan theta=1, then the general value of theta is

(sec^(2)theta-1)/(tan^(2)theta)=?

If 2tan^(2)theta=sec^(2)theta , then the general solution of theta -

If 2tan^(2)theta=sec^(2)theta , then the general solution of theta -

sec^(2)theta=1-tan2 theta

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

If 1/(sin^(2)theta)-1/(cos^(2) theta)-1/(tan^(2)theta)-1/(cot^(2)theta)-1/(sec^(2)theta)-1/(cosec^(2)theta)=-3 then find the value of theta .
