math.cosh(x) Return the hyperbolic cosine of x.

math.cos(x) Return the cosine of x radians.

math.copysign(x, y) Return a float with the magnitude (absolute value) of x but the sign of y. On platforms that support signed zeros, copysign(1.0, -0.0) returns -1.0.

math.ceil(x) Return the ceiling of x, the smallest integer greater than or equal to x. If x is not a float, delegates to x.__ceil__(), which should return an Integral value.

math.atanh(x) Return the inverse hyperbolic tangent of x.

math.atan2(y, x) Return atan(y / x), in radians. The result is between -pi and pi. The vector in the plane from the origin to point (x, y) makes this angle with the positive X axis. The point of atan2() is that the signs of both inputs are known to it, so it can compute the correct quadrant for the angle. For example, atan(1) and atan2(1, 1) are both pi/4, but atan2(-1, -1) is -3*pi/4.

math.atan(x) Return the arc tangent of x, in radians.

math.asinh(x) Return the inverse hyperbolic sine of x.

math.asin(x) Return the arc sine of x, in radians.

math.acosh(x) Return the inverse hyperbolic cosine of x.
