Question

angle of sin 1/root 2​

Answer 1

bhai it's question is wrong .

but I solve it

sin^-1(1/√2)

sin^-1.sin45°

Angle is 45°

Answer 2

Answer:

let y=sin raise to -1(1/root 2)

Hence,

sin y=1/root 2

sin y=sin(pi/4)

Range of principal value of sin raise to -1 is between -pi/2 and pi/2

hence principle value is pi/4(45 degree)
