tan

Trigonometric tangent function.

Syntax

tan(expr)

Argument

expr
A valid scalar, vector, or matrix expression in radians.

Example

Templex Expression Results
{tan(PI/4)} 1
{tan( {0, 1, 2} * PI)} 0, 0, 0
{tan( { {0, 1}, {0.25, 0.75} } * PI)} {0, 0}, {1, -1}

Comments

expr is measured in radians.

If expr is a scalar, the result is a scalar which is the trigonometric tangent of expr.

If expr is a vector, the result is a vector of the same dimensions containing a trigonometric tangent for each element of expr.

If expr is a matrix, the result is a matrix of the same dimensions containing a trigonometric tangent function for each element of expr.
