Question

Python

Numerical integration First add the line from scipy import integrate to the code cell. Define a function f(x) = esin () (this literal assignment does not work in Python, but look at how we did it in the previous exercises). Use integrate.quad to integrate the function from 0 to and print the result. What is the output? Note that the output can be unpacked using int, err - integrate.quad.

Answer 1

Hi,

Please find the code below, I have added comments in the code for the ease of your understanding:

*********** CODE ********

#import modules
from scipy import integrate
import numpy as np
#lambda function of f(x)=esin(x)
f= lambda x:np.exp(1)*np.sin(x)
#Computing the error
err = integrate.quad(f, 0, np.pi)
#unpacking and printing the result
print(*err)

********* SNAPSHOT **********

from scipy import integrate import numpy as np f= lambda x: np.exp(1)*np.sin(x) err = integrate.quad(f, o, np.pi) print(*err) 5.436563656918091 6.035798146750805e-14

I hope it helps,

Please get back to me in comment section for any query.
