Calculators

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

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

Calculates the product of two compatible matrices.

Calculates the dot product (scalar product) of two vectors. The dot product of two vectors is a single number that represents the cosine of the angle between them, scaled by the product of their magnitudes.

Calculates the length (magnitude) of a vector.

Calculates the equation of a line perpendicular to a given line and passing through a specified point. The calculator determines the slope of the perpendicular line, and then uses the point-slope form to find the equation in slope-intercept form (y = mx + b).

This calculator finds the equation of a line parallel to a given line and passing through a specified point. It uses the slope-intercept form (y = mx + b).

Calculates the distance between two points in a Cartesian coordinate system.

Converts a quadratic expression to vertex form by completing the square.

Simplifies a ratio or finds an equivalent ratio given one part.
