Trigonometric functions can help you manage complex calculations involving angles.
|
|
Or maybe they can be used to create pretty pictures. Who knows?

#pi.helper
|
|
%h3
|
|
%a(href="#pi")
|
|
pi()
|
|
.details
|
|
%p
|
|
Returns the value of π.
|
|
|
|
#sin.helper
|
|
%h3
|
|
%a(href="#sin")
|
|
sin($number)
|
|
.details
|
|
%p
|
|
Takes the sine of a number. If the number is unitless or has a unit of <code>deg</code>
|
|
then it will return a unitless result. Degrees will first be converted to radians.
|
|
If the number is any other unit, the units will be passed thru to the result,
|
|
and the number will be treated as radians.
|
|
|
|
#cos.helper
|
|
%h3
|
|
%a(href="#cos")
|
|
cos($number)
|
|
.details
|
|
%p
|
|
Takes the cosine of a number. If the number is unitless or has a unit of <code>deg</code>
|
|
then it will return a unitless result. Degrees will first be converted to radians.
|
|
If the number is any other unit, the units will be passed thru to the result,
|
|
and the number will be treated as radians.
|
|
#tan.helper
|
|
%h3
|
|
%a(href="#tan")
|
|
tan($number)
|
|
.details
|
|
%p
|
|
Takes the tangent of a number. If the number is unitless or has a unit of <code>deg</code>
|
|
then it will return a unitless result. Degrees will first be converted to radians.
|
|
If the number is any other unit, the units will be passed thru to the result,
|
|
and the number will be treated as radians.
