Question

Use Python
Write a program that asks the user to enter the expression of a function to a single variable x. From this expression, using the sympy library, do the following:

Calculate the images for x ranging from 0 to 19

Answer 1

The python code is below

from sympy import *

x=symbols('x') # As there is only one symbol so we define x as our symbol

# taking expression input from the user
exp=sympify(input("enter the expression in form of x as variable:"))

# iterating from 0 to 20 and printing the value of expression.
for i in range(20):
   result=exp.evalf(subs={x:i})
   print('result of expression with x={} is: {:.2f}'.format(i,result))

CODESCREEN SHOT- Maintain the indentation i.e spaces of the above by checking the screen shot.

Make sure you have sympy package installed. If not go to command prompt and type pip install sympy

OUTPUT SCREEN- In the input of expression I have given x+1 . you can also give x*2+4
