MATLAB Function Reference |
Tangent of an argument in radians
Syntax
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 .
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 .
