numpy.fabs(x[, out]) = Compute the absolute values element-wise. This function returns the absolute values (positive magnitude)

numpy.fix(x, y=None)

numpy.tan(x[, out]) = Compute tangent element-wise. Equivalent to np.sin(x)/np.cos(x) element-wise.

numpy.arctan2(x1, x2[, out]) = Element-wise arc tangent of x1/x2 choosing the quadrant correctly. The quadrant

numpy.prod(a, axis=None, dtype=None, out=None, keepdims=False)

numpy.cumsum(a, axis=None, dtype=None, out=None)

numpy.copysign(x1, x2[, out]) = Change the sign of x1 to that of x2, element-wise. If both arguments are arrays or sequences

numpy.sum(a, axis=None, dtype=None, out=None, keepdims=False)

numpy.cross(a, b, axisa=-1, axisb=-1, axisc=-1, axis=None)

numpy.exp2(x[, out]) = Calculate 2**p for all p in the input array.
