Derivative of $x^{4}$

The derivative of x^4 is 4 x^3.

The derivative of $x^{4}$ is $4 x^{3}$ .

f(x) =

\frac{d}{dx}\left[x^{4}\right] = 4 x^{3}

Type any function of x; the derivative is computed symbolically in your browser.

\frac{d}{dx}\left[x^{4}\right] = 4 x^{3}

Graph of f(x) = x^4 and its derivative. The dashed line is the tangent at x = 1; its slope is f'(1) = 4.

How to work it out

1
We differentiate $f(x) = x^{4}$ with respect to x. The rule that applies is the standard derivative.
$f(x) = x^{4}$
2
This is a standard derivative from the table.
3
Simplify:
$f'(x) = 4 x^{3}$
4
Differentiating once more gives the second derivative, which tells you about curvature:
$f''(x) = 12 x^{2}$
