Answer 2

Given:

$sin^{2}A*cosec^{2}A=1$

Answer: $sin^{2}A*cosec^{2}A=1$

Step-by-step explanation:

We know that cosec A = 1 / sin A

Sub. this in LHS  CosecA , We get,

      LHS =>

                     $sin^{2}A*(\frac{1}{sinA} )^{2}\\\\=>sin^{2}A*\frac{1}{sin^{2}A} \\\\=>1$

                           = RHS

Hence proved

Hope helps and mark as brainliest plz
