" Prove that "tan A+cot A=2cosec2A

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

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

tan A + cot A = 2 cosec 2A

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

Prove that: "tan"A+cotA=2"cosec" 2A and deduce that "tan" 75^(@)+cot 75^(@)=4 .

Prove that tan A - cot A =-2 cot2A

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

Prove that: cotA-cot2A="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

If csc A+sec A=csc B+sec B, prove that: tan A tan B=cot(A+B)/(2)
