Logarithms & Trigonometry

Logarithms

Function	Name	Behaviour
exp()	Exponential	Calculates the value of e to the power of x, where e is the base of the natural logarithm. exp(1) returns Euler's number.
ln()	Natural logarithm	The natural logarithm of a number is its logarithm to the base of the mathematical constant e.
log2()	Base 2 logarithm	Calculate the base 2 logarithm of a value
log(), log10()	Base 10 logarithm	Calculate the base 10 logarithm of a value

Log to any base

log 20 base 4                            | 2.1609640474

81 is 9 to what power                    | 2
27 is 3 to the what                      | 3

Trigonometry 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 trigonometry 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
