math functions

This page lists scalar math functions. Inputs are converted to real; outputs are real.

• sin(x) — sine of x radians.
• cos(x) — cosine of x radians.
• tan(x) — tangent of x radians.
• asin(x) / asin2(x) — arcsine of x (radians).
• acos(x) / acos2(x) — arccosine of x (radians).
• atan(x) — arctangent of x (radians).
• atan2(y, x) — arctangent using signs of y and x (radians).
• pow(base, exponent) — base raised to exponent.
• pi() — constant π.
• radians(degrees) — converts degrees to radians.
• degrees(radians) — converts radians to degrees.

Examples

Basic trig:

datatable(angle:real)[0, 1.5707963267948966]
| extend s = sin(angle), c = cos(angle), t = tan(angle)

angle	s	c	t
0	0	1	0
1.5707963267948966	1	0	1.633123935319537e+16

Inverse trig:

datatable(v:real)[-1, 0, 1]
| extend a_sin = asin(v), a_cos = acos(v), a_tan = atan(v)

v	a_sin	a_cos	a_tan
-1	-1.5707963267948966	3.141592653589793	-0.7853981633974483
0	0	1.5707963267948966	0
1	1.5707963267948966	0	0.7853981633974483

Powers and constants:

print eight = pow(2, 3), pi_val = pi()

eight	pi_val
8	3.141592653589793

Degree/radian conversion:

datatable(deg:real)[0, 180]
| extend rad = radians(deg), back = degrees(rad)

deg	rad	back
0	0	0
180	3.141592653589793	180
