Trigonometric functions

Function	Name
sin()	Calculate the sine of a value
sinh()	Calculate the hyperbolic sine of a value
asinh()	Calculate the hyperbolic arcsine of a value
cos()	Calculate the cosine of a value
cosh()	Calculate the hyperbolic cosine of a
acosh()	Calculate the hyperbolic arccos of a value
tan()	Calculate the tangent of a value
tanh()	Calculate the hyperbolic tangent of a value
atanh()	Calculate the hyperbolic arctangent of a value

Trigonometric functions take a value in radians by default.

If you want to use degrees, specify this in the parameter, or append "d" to the function name:

sin(90 degrees) = 1.0

sind(90) = 1.0

Inverse trigonometric functions

Function	Name
asin()	Calculate the inverse sine of a value
acos()	Calculate the inverse cosine of a value
atan()	Calculate the inverse tangent of a value

Inverse trigonometric functions return a value in radians by default.

If you want to use degrees, specify this in the parameter, or append "d" to the function name:

asin(0.5 degrees) = 30º

asind(0.5) = 30º
