However, the central difference yields a more accurate approximation.

However, it can be used to obtain more accurate approximations for the derivative.

As shown, after only the fifth winding, the distance is a 99.97% accurate approximation to π.

In mathematics, a mathematical approach to finding an accurate approximation to a problem's solution.

That is a very accurate approximation of what happened.

Recently discovered and highly accurate approximation for the construction of a regular heptagon.

The bird calls are shrilly accurate, or at least reasonable approximations.

However, it is likely that a better one will be needed when a more accurate approximation is required.

As the number of sides increases, it becomes a more accurate approximation of a circle.

These were the most accurate approximations of π after almost a thousand years.
