Calculators

Calculates the average where some data points contribute more weight than others.

Calculates the angle whose sine is a given number. The result is in radians.

Visualizes the graph of a polynomial function by calculating and plotting points.

This calculator demonstrates the behavior of floating-point numbers in calculations and highlights potential precision issues due to the way computers store and manipulate these numbers. It allows you to input two numbers and an operation, then displays the result and the difference between the calculated result and a more precise value.

Calculates the angle whose tangent is a given number.

Performs long division or synthetic division for polynomial expressions.

Solves for missing sides or angles in a right-angled triangle using trigonometric functions (sine, cosine, tangent).

Calculates the angle whose cosine is a given number. The result is given in degrees.

Calculates the volume, surface area, or diameter of a sphere given its radius.

Calculates the number of combinations (nCr) - the number of ways to choose k items from a set of n items, where order doesn't matter.
