| riemann integral |
$\int_0^1 x^2 \mathrm{d}x = \frac{1}{3}$
|
The Riemann integral of $x^2$ on $[0, 1]$ is $\frac{1}{3}$, because $\frac{x^3}{3}$ is an antiderivative.

| lebesgue integral |
$\frac{1}{3}$
|
The Lebesgue integral of $x^2$ on $[0, 1]$ equals its Riemann integral, as for every Riemann integrable function.
|
| locally Lipschitz continuous |
✓ |
$x \mapsto x^2$ on $[0, 1]$ is locally Lipschitz continuous, because the function is Lipschitz continuous on all of $[0, 1]$ with constant $2$.
|
| Lipschitz continuous |
✓ |
$x \mapsto x^2$ on $[0, 1]$ is Lipschitz continuous because that derivative is at most $2$ on $[0, 1]$.
|
| continuously differentiable |
✓ |
$x \mapsto x^2$ on $[0, 1]$ is continuously differentiable because its derivative $2x$ is continuous.
|
| absolutely continuous |
✓ |
$x \mapsto x^2$ on $[0, 1]$ is absolutely continuous, because it is Lipschitz continuous.
|
| continuous |
✓ |
$x \mapsto x^2$ on $[0, 1]$ is continuous.
|
| uniformly continuous |
✓ |
$x \mapsto x^2$ on $[0, 1]$ is uniformly continuous because every continuous function on a compact set is uniformly continuous.
