Question

if sin-¹x + sin-¹y = π then value of ( x 100 + y200) ( x 100 - y 200 ) is equal to​

Answer 1

Correct option is

A

0Given, sin −1

x+sin

−1 y+sin

−1

z= 23π

This will happen only when sin

−1

x=sin

−1

y=sin

−1

z=

2

π

Since sin

−1

x∈[−

2

π ,

2π

]then =sin

2

π

=1⇒x=y=z=1

Hence desired value is =1+1+1+−

1+1+1

9 =3− 39 =0
