सिद्ध कीजिए कि `2+(1)/(tan ^(2)theta)+(1)/(cot^(2)theta)=sec ^(2)theta+cosec ""^(2)theta`

tan^(2)theta+cot^(2)theta+2=sec^(2)theta cosec^(2)theta

Prove: tan^(2)theta+cot^(2)theta+2=sec^(2)theta.cosec^(2)theta .

prove that tan^(2)theta+cot^(2)theta=sec^(2)theta+cosec^(2)theta-2

(sec^(2)theta-sin^(2)theta)/(tan^(2)theta)=cosec^(2)theta-cos^(2)theta

prove that: tan^(2) theta-cot^(2) theta=sec^(2) theta- cosec^(2) theta

Prove : cot^(2) theta-tan^(2)theta=cosec^(2)theta-sec^(2)theta

Prove: cot^(2)theta- tan^(2) theta=cosec^(2)theta-sec^(2)theta .

((1+tan^(2)theta)cot theta)/(csc^(2)theta)=tan 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 .
