In sympy, cos() method is cosine function. Using the cos(x) method in the sympy module, we can compute the cosine of x.
Syntax : sympy.cos(x) Return : Returns the cosine of x
Code #1: Below is the example using cos() method to find cosine function.
Python3
# importing sympy libraryfrom sympy import *# calling cos() method on expressiongeek1 = cos(-1)geek2 = cos(pi / 3)geek3 = cos(pi)print(geek1)print(geek2)print(geek3) |
Output:
cos(1) 1/2 -1
Code #2:
Python3
# importing sympy libraryfrom sympy import *# calling cos() method on expressiongeek = cos(2 + 5j)print(geek) |
Output:
-30.8822353189167 - 67.4727884405875*I
