Question

Solve for x: sin^(-1)(1-x)-2sin^(-1)x= π/2

Answer 1

sin^(-1) is inverse sine, right?

Answer 2

\[\sin^{-1}(1-x)-2\sin^{-1}x= π/2\]

Answer 3

It is sin inverse

Answer 6

Steps please?

Answer 7

take sin inverse (1-x) as alpha and sin inverse x as theta
sin(alpha-2theta)=sin(pi/2)
sinalphacos2thta-cosalphasin2theta=sinpi/2
apply the corresponding values then u vl get the answr
