Python | sympy.acsc() method

sympy.acsc() is a function in the SymPy library, a Python library for symbolic mathematics. The function acsc() returns the arc cosecant (inverse cosecant) of a given number or expression.

Here's a basic introduction to the acsc() function:

Importing the necessary modules:

from sympy import acsc, symbols, pi from sympy.abc import x 

Basic usage:

• For a number:

print(acsc(1)) # This will give pi/2 

• For a symbol or expression:

expr = acsc(x) print(expr) 

• Evaluation at a specific value:

value_at_point = expr.subs(x, 1) print(value_at_point) # This will also give pi/2 

• Numerical Evaluation: To get a float result:

numerical_value = acsc(1).evalf() print(numerical_value) 

Remember, the domain of acsc() is -�� to -1 union 1 to ��. It's not defined for values between -1 and 1 because the cosecant function doesn't have values in that range.
