Question

Prove that 2cosec2A-cotA=tanA

Answer 1

Answer:

here is your answer

Step-by-step explanation:

tan A+cot A =2cosec2A

LHS

sin A/cos A + cosA/sin A

(sin^2A+ cos^2A)/sin A cosA

2/2sinA cosA

2/sin2A

2cosec2A

so LHS=RHS

Answer 2

Answer:

easiest way u can find..here

Step-by-step explanation:

cotA+tanA-cotA=tanA....(don't worry how I got cotA+tanA in the place of 2cosec2A; )

substitute i.e2cosec2A=cotA+tanA...

just one step answer is fasak hope this helps u!!!
