$tan returns the tangent of an angle of N radians
Synopsis[edit]
$tan(<N>)[.deg]
Switches[edit]
None
Parameters[edit]
NThis is the angle in radians for which you wish to retrieve the tangent.
Properties[edit]
degSees N as degrees in a 360 degree circle instead of radians.
Example[edit]
Tangent is the ratio of the Opposite Side / Adjacent Side of a right triangle, so in a right triangle from the position of an angle of 30 degrees, the length of the Opposite side is .57735 as long as the Adjacent side. As with $calc(), the returned fraction is limited to 6 decimal places.
//echo -a There are 2x pi radians in a circle, so a radian is $calc(360 / (2*$pi) ) degrees //var %i 30 | echo -a $tan(%i).deg is the same as $tan( $calc(%i * $pi / 180) ) except for rounding
$tan accepts numbers larger than 1 rotation of a circle, as if the angle loops past the origin and continues. Assuming you are using the .deg property, angles above 360 degrees return the same result of the angle modulo 360.
//var %i 400 | echo -a $tan(%i).deg is the same as $tan( $calc(%i % 360) ).deg
