dy/dx = (5x^4)/sqrt(1-x^10)dydx=5x41x10

Explanation:

Use the derivative of arcsinarcsin and the chain rule.

d/dx (arcsinx) = 1/sqrt(1-x^2)ddx(arcsinx)=11x2

When we don't have xx as the argument of the function, then we need the chain rule:

d/dx (arcsinu) = 1/sqrt(1-u^2) (du)/dxddx(arcsinu)=11u2dudx

So, we get:

For y = arcsin(x^5)y=arcsin(x5),

dy/dx = 1/sqrt(1-(x^5)^2) d/dx(x^5)dydx=11(x5)2ddx(x5)

= (5x^4)/sqrt(1-x^10)=5x41x10
