cot A-cot2A=csc2A

Prove that: cotA-cot2A="cosec"2A

Prove that: cotA-cot2A="cosec"2A

cosec A- 2cot 2A cos A=

prove that tan A+cot A=2 cosec 2A

Show that tan A+cot A=2 cosec 2A

csc2A+cot2A=?

( cos A - sin A + 1 ) / ( cos A + sin A - 1 ) = cosec A + cot A cosec A + cot A , = using the identity cosec ^ 2 A = 1 + cot^ 2 A .

If A+B+C =pi , show that cot A + cot B+cot C-cosec A *cosec B* cosec C = cot A*cot B*cot C .

The value of (cosec 2A - cot 2A) is-

tan A + cot A = 2 cosec 2A
