The module also defines two mathematical constants:
acos(x) Return the arc cosine of x.
asin(x) Return the arc sine of x.
atan(x) Return the arc tangent of x.
atan2(y, x) Return atan(y / x).
ceil(x) Return the ceiling of x as a float.
cos(x) Return the cosine of x.
cosh(x) Return the hyperbolic cosine of x.
degrees(x) Converts angle x from radians to degrees.
exp(x) Return e**x.
fabs(x) Return the absolute value of x.
floor(x) Return the floor of x as a float.
fmod(x, y) Return fmod(x, y), as defined by the platform C library. Note that the Python expression x % y may not return the same result.
frexp(x) Return the mantissa and exponent of x as the pair (m, e). m is a float and e is an integer such that x == m * 2**e. If x is zero, returns (0.0, 0), otherwise 0.5<= abs(m)< 1.
hypot(x, y) Return the Euclidean distance, sqrt(x*x + y*y).
ldexp(x, i) Return x * (2**i).
log(x[, base]) Returns the logarithm of x to the given base. If the base is not specified, returns the natural logarithm of x. Changed in version 2.3: base argument added.
log10(x) Return the base-10 logarithm of x.
modf(x) Return the fractional and integer parts of x. Both results carry the sign of x. The integer part is returned as a float.
pow(x, y) Return x**y.
radians(x) Converts angle x from degrees to radians.
sin(x) Return the sine of x.
sinh(x) Return the hyperbolic sine of x.
sqrt(x) Return the square root of x.
tan(x) Return the tangent of x.
tanh(x) Return the hyperbolic tangent of x. Note that frexp() and modf() have a different call/return pattern than their C equivalents: they take a single argument and return a pair of values, rather than returning their second return value through an `output parameter' (there is no such thing in Python).
pi The mathematical constant pi.
e The mathematical constant e.
