Question

anyone pls???i ll mark the most relevant ans as brainliest​

Answer 1

2y= sin^-1. ( 2xy/( x^2 + y^2)

Sin 2y = 2xy/( x^2 +y^2)

2 sin y cosy = 2xy/( x^2 + y^2)

siny cosy = xy/( x^2 + y^2)

sin y cosy = x/√(x^2 + y^2). y/( √x^2 + y^2)

Compare

siny = x/√x^2 + y^2, cosy= y/√x^2 + y^2

Siny = x/√x^2 + y^2

sin^2 y = x^2/x^2 + y^2

sin^2y x^2 + sin^2 y y^2 = x^2

x^2 ( 1- sin^2 y ) = sin^2 y y^2

x= y sin y/cosy

= y tany

As x>y

x/y >1

x/y = tan y

tany>1

x= y/tany = 1
