Python has a built-in math module that we can use for mathematical tasks. This module provides access to the mathematical functions defined by the C standard.

The following functions are provided by this module. Except when explicitly noted otherwise, all return values are floats.

Math Module

.asin()
Returns the arcsine of a value, giving an angle in radians between `-π/2` and `π/2` for inputs ranging from `-1` to `1`
.comb()
Calculates the number of ways to choose `k` items from `n` items without regard to order or repetition.
.isclose()
Determines if two floating-point numbers are close to each other within a specified tolerance.
math.acos()
Returns the arc cosine of a number.
math.acosh()
Computes the inverse hyperbolic cosine of a number.
math.asinh()
Returns the inverse hyperbolic sine of a given number.
math.atan()
Returns the inverse tangent of a number.
math.atan2()
Returns the arc tangent of the quotient of its two arguments in radians.
math.atanh()
Returns the inverse hyperbolic tangent of a number.
math.ceil()
Takes in a numeric data type and rounds the value up to the nearest integer.
math.copysign()
Takes two numeric values and returns a float with the magnitude (absolute value) of the first value and the sign of the second value.
math.cos()
Returns the cosine of an angle.
math.cosh()
Returns the hyperbolic cosine of a number.
math.degrees()
Returns the degree equivalent of an input angle given in radians.
math.erf()
Returns the error function of a number.
math.erfc()
Finds the complementary error function of a number.
math.exp()
Returns e raised to the power of x.
math.fabs()
Computes the absolute value of a number and returns it as a floating-point value.
math.factorial()
Returns factorial of a number.
math.floor()
Takes in a numeric data type and rounds the value down to the nearest integer.
math.frexp()
Returns the mantissa and the exponent of a given number as a tuple.
math.fsum()
Computes the precise floating-point sum of an iterable of numbers.
math.gcd()
Returns the Greatest Common Divisor (GCD) of two or more integers.
math.isfinite()
Checks whether a given number is finite or not.
math.isinf()
Returns a boolean indicating whether the given value is infinite or not.
math.isnan()
Returns a boolean indicating whether the given value is "Not a Number" (NaN).
math.log()
Returns the natural logarithm of a number or the logarithm of a number to the given base.
math.pow()
Returns the float value of x raised to the power of y.
math.radians()
Returns the radian equivalent of an input angle given in degrees.
math.remainder()
Returns the remainder of x divided by y
math.sin()
Returns the sine of input numeric x, measured in radian value.
math.sqrt()
Returns the square root of numeric input x.
math.tan()
Returns the tangent of input numeric x, measured in radians.
