Mathematical functions

I will focus on the important ones.

Trigonometric functions

sin(x, /[, out, where, casting, order, ...])	Trigonometric sine, element-wise.
cos(x, /[, out, where, casting, order, ...])	Cosine element-wise.
tan(x, /[, out, where, casting, order, ...])	Compute tangent element-wise.
arcsin(x, /[, out, where, casting, order, ...])	Inverse sine, element-wise.
arccos(x, /[, out, where, casting, order, ...])	Trigonometric inverse cosine, element-wise.
arctan(x, /[, out, where, casting, order, ...])	Trigonometric inverse tangent, element-wise.
hypot(x1, x2, /[, out, where, casting, ...])	Given the "legs" of a right triangle, return its hypotenuse.
arctan2(x1, x2, /[, out, where, casting, ...])	Element-wise arc tangent of x1/x2 choosing the quadrant correctly.
degrees(x, /[, out, where, casting, order, ...])	Convert angles from radians to degrees.
radians(x, /[, out, where, casting, order, ...])	Convert angles from degrees to radians.
unwrap(p[, discont, axis, period])	Unwrap by taking the complement of large deltas with respect to the period.
deg2rad(x, /[, out, where, casting, order, ...])	Convert angles from degrees to radians.
rad2deg(x, /[, out, where, casting, order, ...])	Convert angles from radians to degrees.

Rounding

round(a[, decimals, out])	Evenly round to the given number of decimals.
around(a[, decimals, out])	Round an array to the given number of decimals.
rint(x, /[, out, where, casting, order, ...])	Round elements of the array to the nearest integer.
fix(x[, out])	Round to nearest integer towards zero.
floor(x, /[, out, where, casting, order, ...])	Return the floor of the input, element-wise.
ceil(x, /[, out, where, casting, order, ...])	Return the ceiling of the input, element-wise.
trunc(x, /[, out, where, casting, order, ...])	Return the truncated value of the input, element-wise.
