How to Use

Trigonometric functions (sin, cos, tan) accept values in radians. To convert degrees to radians, multiply by π/180 (approximately 0.01745).

log (natural logarithm) uses base e ≈ 2.71828, while log10 uses base 10. For example, log(100) ≈ 4.605, but log10(100) = 2.

exp(x) computes e raised to the power x, where e ≈ 2.71828. It is the inverse of the natural logarithm.

ceil rounds a number up to the nearest integer, while floor rounds it down. For example, ceil(4.2) = 5 and floor(4.9) = 4.
