$sin returns the sine of an angle of N radians.
Synopsis[edit]
$sin(<N>)[.deg]
Parameters[edit]
- N -This is the angle in radians for which you wish to retrieve the sine.
You can use the letter 'e' or 'd' as *10^N, $sin(5e6) = $sin($calc(5*10^6))
Properties[edit]
- deg - Sees N as degrees in a 360 degree circle instead of radians.
Example[edit]
Sine is the ratio of the Opposite Side / Hypotenuse of a right triangle, so in a right triangle from the position of an angle of 60 degrees, the length of the Opposite side is .866025 as long as the hypotenuse. 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 60 | echo -a $sin(%i).deg is the same as $sin( $calc(%i * $left($pi,8) / 180) )
$sin 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 $sin(%i).deg is the same as $sin( $calc(%i % 360) ).deg
Compatibility[edit]
Added: mIRC v5.3
Added on: 13 Dec 1997
Note: Unless otherwise stated, this was the date of original functionality.
Further enhancements may have been made in later versions.
