Trigonometric Functions

sin() Sine function (radians). sin(PI/2) = 1

cos() Cosine function (radians). cos(0) = 1

tan() Tangent function (radians). tan(PI/4) = 1

asin() Arcsine (inverse sine, radians). asin(1) = PI/2 ≈ 1.57

acos() Arccosine (inverse cosine, radians). acos(0) = PI/2 ≈ 1.57

atan() Arctangent (inverse tangent, radians). atan(1) = PI/4 ≈ 0.785

Root Functions
