Answer:

[tex]sin(cos^{-1}x)=\sqrt{1-x^2}[/tex]

Step-by-step explanation:

let us assume

[tex]cos^{-1} x=\theta\\x=cos\theta\\[/tex]

now

[tex]sin(cos^{-1}x)[/tex] can be written as [tex]sin\theta[/tex]

we know  [tex]sin^2\theta+cos^2\theta=1[/tex]

so [tex]sin^2\theta=1-cos^2\theta[/tex]

[tex]sin\theta=\sqrt{1-cos^2\theta}[/tex]

now from above equation we can say that

[tex]sin\theta=\sqrt{1-x^2}[/tex]

[tex]sin(cos^{-1}x)=\sqrt{1-x^2}[/tex]
