Calculators

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

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

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.

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 odds and probabilities, converting between the two and determining odds from event counts.

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

Calculates the probability that at least two people in a group share the same birthday.

Calculates the angle whose tangent is a given number.

Calculates the number of combinations (binomial coefficient) of choosing k items from a set of n items.
