" 2.Prove that "sqrt(sec^(2)theta+cosec^(2)theta)=tan theta+cot theta

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

Prove the following identity : sqrt (sec^2 theta+ cosec^2 theta)= tan theta+ cot theta= sec theta cosec theta .

Prove that (1 +cot theta -cosec theta )(1+tan theta +sec theta )=2.

Prove that (1+cot theta - cosec theta)(1+tan theta + sec theta) =2 .

Prove that 2 sec ^(2) theta-2 cosec^2theta-sec ^(4) theta+cosec^4 theta=cot ^(4) theta-tan ^(4) theta

(sec theta+csc theta)^(2)-(tan theta+cot theta)^(2)=

Prove that 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

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

Prove that (1+cot theta - "cosec" theta )(1+ tan theta +sec theta )=2.
