tan - Tangent of argument in radians

Syntax

Y = tan(X)

Description

The tan function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.

Y = tan(X) returns the circular tangent of each element of X.

Examples

Graph the tangent function over the domain .

x = (-pi/2)+0.01:0.01:(pi/2)-0.01;
plot(x,tan(x)), grid on

The expression tan(pi/2) does not evaluate as infinite but as the reciprocal of the floating point accuracy eps since pi is only a floating-point approximation to the exact value of .

Definitions

The tangent can be defined as
