Proof of the identity 1 + cot^2(theta) = cosec^2(theta) |Proved cot^2(x) + 1 = cosec^2(x)
1+cot^2 theta = tan^2 theta Proof
`S=cosecx+cosec�2x+cosec�4x+�+cosec�2nx=cot(x/2)?cot2nx`

等式を証明せよ: `tan^(2)theta+cot^(2)theta +2=sec^(2)theta cosec^(2)theta`
The value of The value of 〖tan〗^2 (〖sec〗^(-1) 2)+ 〖cot〗^2 (〖cosec〗^(-1) 3) is: (a) 5 (b)11(c)13(d)15
