`(1+tan theta+sec theta)(1+cot theta-cosec theta) = ?` (a) `-1` (b) `0` (c) `2`

(b) cosec theta=1+cot theta

(b) cosec theta=1+cot theta

What is the value of (tan theta cosec theta)^(2)-(sin theta sec theta)^(2) (a) -1 (b) 0 (c) 1 (d) 2

Solve cot theta + tan theta=2 cosec theta .

Prove that : (sin theta + sec theta) ^(2) + (cos theta + cosec theta) ^(2) = (1 + sec theta cosec theta) ^(2).

(2sec theta+3 tan theta+5 sin theta -7cos theta+5)/(2tan theta+3 sec theta+5 cos theta +7sin theta+8)= (a) tan (theta/2) (b) cot (theta/2) (c) sec (theta/2) (d) cosec (theta/2)

1/sec2(theta) + 1/cosec2(theta) =

Prove that cot 2 theta + tan theta = cosec 2 theta

Prove that (sin theta- "cosec" theta )(cos theta- sec theta )=(1)/(tan theta + cot theta).

prove that : (tan 2^n theta)/(tan theta) = (1+sec 2theta) (1+ sec 2^2 theta) (1+sec 2^3 theta) … (1+ sec 2^n theta)
