The {{tan}} circular function template returns the tangent of , where is a real number expressing a circular angle in radians.
Note that you may also use the tan operator (used within the {{#expr: }} parser function extension, e.g. {{#expr: tan (pi/6) }}) which also takes a circular angle in radians as argument.
