[" Example 5.Prove that : "],[" i) tan "A+cot A=2cosec2A]

tan A + cot A = 2 cosec 2A

Prove that tan A + cot A = 2 "cosec 2A" .

Prove that: tan(A/2)+ cot(A/2)=2 "cosec"A

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

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

If A is not an integral multiple of (pi)/(2) , prove that (i) tan A + cot A= 2 cosec 2 A (ii) cot A - tan A = 2cot 2A

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

Prove the identity : tan A + cot A = sec A . cosec A

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

Prove that : (cot^(2) A)/(cosec A - 1) - 1 = cosec A
