## Derivative of cube root

The derivative of the cube root is equal to 1/(3*("cube_root"(x))^2)=1/(3*(root(3)(x))^2).

## Antiderivative of cube root

The antiderivative of the cube root is equal to 3/4*(x)^(4/3)=3/4*(root(3)(x))^4.

## Limits of cube root

The limits of the cube root exist at -oo (minus infinity) and +oo (plus infinity):
• The cube root function has a limit in -oo which is -oo.
• lim_(x->-oo)root(3)(x)=-oo
• The cube root function has a limit in +oo which is +oo.
• lim_(x->+oo)root(3)(x)=+oo
