Logarithms & Trigonometry

Logarithms and trigonometric functions. Trig comes in degree and radian variants.

Logarithms

.log() → number

Base-10 logarithm.

.ln() → number

Natural (base-e) logarithm.

log (100).log()  // 2
log (100).ln()   // 4.605170185988092

Trigonometry (degrees)

Method	Description
.sin()	Sine (input in degrees).
.cos()	Cosine (input in degrees).
.tan()	Tangent (input in degrees).
.asin()	Arcsine (result in degrees).
.acos()	Arccosine (result in degrees).
.atan()	Arctangent (result in degrees).

log (30).sin()   // 0.5
log (180).cos()  // -1

Trigonometry (radians)

Method	Description
.radSin()	Sine (input in radians).
.radCos()	Cosine (input in radians).
.radTan()	Tangent (input in radians).

Convert between the two with the built-in functions degtorad(d) and radtodeg(r). The full set of mathematical functions and constants lives in the math package.
