cosec^2 A - 1 = cot^2 A
Cot A = Cos A * cosec A
Hence proved

i cant show it properly though my keyboard.
but it is very simple you can try it
first cosec^2A-1 is cot^2A
now after taking square root it will become cotA
cot A is cosA/sinA
we can also write it as cosA.cosecA as 1/sinA is cosecA
sorry for not writing in equation form
