Calculators

Solves proportion problems (e.g., finding a missing value in 'a/b = c/d').

Calculates the factorial (n!) of a non-negative integer.

Converts a decimal number into its equivalent fraction.

Calculates the sine of an angle (given in degrees or radians).

Calculates the length (magnitude) of a vector.

Calculates the slope (gradient) of a line given two points.

Provides trigonometric function values (sin, cos, tan) for angles around the unit circle.

Calculates the inverse of a 2x2 or 3x3 square matrix. The inverse matrix is calculated if it exists. If the determinant is zero, the matrix is not invertible.

Solves equations involving absolute value expressions.

This calculator factors a trinomial expression of the form ax² + bx + c into the product of two binomials.
