Python: Get the details of math module
Math Module Details
Write a Python program to get the details of the math module.
Sample Solution-1:
Python Code:
# Imports the math module
import math
# Use the 'dir' function to get a list of names in the 'math' module, including functions and constants.
# Store this list in the 'math_ls' variable.
math_ls = dir(math)
# Print the list of names in the 'math' module, which includes mathematical functions and constants.
print(math_ls)
Sample Output:

Sample Solution-2:
Python Code:
# Import the 'math' module to access mathematical functions and constants.
import math
# Print a message to provide details about the 'math' module.
print("Details of math module:\n")
# Use the 'help' function to display the documentation and details of the 'math' module.
# The 'help' function will show information about available functions, constants, and how to use them.

NAME
math
DESCRIPTION
This module is always available. It provides access to the
mathematical functions defined by the C standard.
FUNCTIONS
acos(...)
acos(x)
Return the arc cosine (measured in radians) of x.
acosh(...)
acosh(x)
Return the inverse hyperbolic cosine of x.
asin(...)
asin(x)
Return the arc sine (measured in radians) of x.
asinh(...)
asinh(x)
Return the inverse hyperbolic sine of x.
atan(...)
atan(x)
Return the arc tangent (measured in radians) of x.
atan2(...)
atan2(y, x)
Return the arc tangent (measured in radians) of y/x.
Unlike atan(y/x), the signs of both x and y are considered.
atanh(...)
atanh(x)
Return the inverse hyperbolic tangent of x.
ceil(...)
ceil(x)
Return the ceiling of x as an Integral.
This is the smallest integer >= x.
copysign(...)
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.
cos(...)
cos(x)
Return the cosine of x (measured in radians).
cosh(...)
cosh(x)
Return the hyperbolic cosine of x.
degrees(...)
degrees(x)
Convert angle x from radians to degrees.
erf(...)
erf(x)
Error function at x.
erfc(...)
erfc(x)
Complementary error function at x.
exp(...)
exp(x)
Return e raised to the power of x.
expm1(...)
expm1(x)
Return exp(x)-1.
This function avoids the loss of precision involved in the direct evaluation of exp(x)-1 for small x.
fabs(...)
fabs(x)
Return the absolute value of the float x.
factorial(...)
factorial(x) -> Integral
Find x!. Raise a ValueError if x is negative or non-integral.
floor(...)
floor(x)
Return the floor of x as an Integral.
This is the largest integer <= x.
fmod(...)
fmod(x, y)
Return fmod(x, y), according to platform C. x % y may differ.
frexp(...)
frexp(x)
Return the mantissa and exponent of x, as pair (m, e).
m is a float and e is an int, such that x = m * 2.**e.
If x is 0, m and e are both 0. Else 0.5 <= abs(m) < 1.0.
fsum(...)
fsum(iterable)
Return an accurate floating point sum of values in the iterable.
Assumes IEEE-754 floating point arithmetic.
gamma(...)
gamma(x)
Gamma function at x.
gcd(...)
gcd(x, y) -> int
greatest common divisor of x and y
hypot(...)
hypot(x, y)
Return the Euclidean distance, sqrt(x*x + y*y).
isclose(...)
isclose(a, b, *, rel_tol=1e-09, abs_tol=0.0) -> bool
Determine whether two floating point numbers are close in value.
rel_tol
maximum difference for being considered "close", relative to the
magnitude of the input values
abs_tol
maximum difference for being considered "close", regardless of the
magnitude of the input values
Return True if a is close in value to b, and False otherwise.
For the values to be considered close, the difference between them
must be smaller than at least one of the tolerances.
-inf, inf and NaN behave similarly to the IEEE 754 Standard. That
is, NaN is not close to anything, even itself. inf and -inf are
only close to themselves.
isfinite(...)
isfinite(x) -> bool
Return True if x is neither an infinity nor a NaN, and False otherwise.
isinf(...)
isinf(x) -> bool
Return True if x is a positive or negative infinity, and False otherwise.
isnan(...)
isnan(x) -> bool
Return True if x is a NaN (not a number), and False otherwise.
ldexp(...)
ldexp(x, i)
Return x * (2**i).
lgamma(...)
lgamma(x)
Natural logarithm of absolute value of Gamma function at x.
log(...)
log(x[, base])
Return the logarithm of x to the given base.
If the base not specified, returns the natural logarithm (base e) of x.
log10(...)
log10(x)
Return the base 10 logarithm of x.
log1p(...)
log1p(x)
Return the natural logarithm of 1+x (base e).
The result is computed in a way which is accurate for x near zero.
log2(...)
log2(x)
Return the base 2 logarithm of x.
modf(...)
modf(x)
Return the fractional and integer parts of x. Both results carry the sign
of x and are floats.
pow(...)
pow(x, y)
Return x**y (x to the power of y).
radians(...)
radians(x)
Convert angle x from degrees to radians.
sin(...)
sin(x)
Return the sine of x (measured in radians).
sinh(...)
sinh(x)
Return the hyperbolic sine of x.
sqrt(...)
sqrt(x)
Return the square root of x.
tan(...)
tan(x)
Return the tangent of x (measured in radians).
tanh(...)
tanh(x)
Return the hyperbolic tangent of x.
trunc(...)
trunc(x:Real) -> Integral
Truncates x to the nearest Integral toward 0. Uses the __trunc__ magic method.
