CalcTree supports a full range of trigonometric and hyperbolic functions using . All trigonometric functions operate using radians by default.
To convert degrees to radians, use:
To convert radians to degrees:
sin(x)
Sine
sin(pi / 2) → 1

Cosine
cos(0) → 1
tan(x)
Tangent
tan(pi / 4) → 1
cot(x)
Cotangent
cot(pi / 4) → 1
sec(x)
Secant
sec(0) → 1
csc(x)
Cosecant
csc(pi / 2) → 1
asin(x)
Inverse sine
asin(1) → pi / 2
acos(x)
Inverse cosine

All trigonometric functions use radians by default.
Inputs can include units (e.g., degrees), but they must be converted to radians manually for most trigonometric functions.
Results are unitless unless explicitly wrapped in unit conversion logic.
