To simplify calculations or estimate complex functions.

Adjusts a number to the nearest specified value.

Cutting off digits without rounding them up.

To indicate the precision of a measured value.

Using the tangent line at a point on a curve.

Expressions of the form $(1 + x)^n$ for small $x$.

Expands a function into an infinite sum of terms.

$5.7$ is the result when rounded to one decimal place.

Truncated value is $5.67$ when cut off at two decimal places.

$f(x) ≈ f(a) + f'(a)(x - a)$.
