Python Coding challenge - Day 399| What is the output of the following Python Code?

 

Code Explanation:

from sympy import symbols, diff

symbols('x'): Creates a symbolic variable 

𝑥

x that can be used in algebraic expressions.

diff(): Computes the derivative of a given function.

 

Define the function 

f(x)

x = symbols('x')  

f = x**3 + 5*x**2 - 2*x + 7  

This defines the function:

f(x)=x 3+5x 2−2x+7

Compute the Derivative 

derivative = diff(f, x)

diff(f, x) calculates the first derivative of 

f(x).

Evaluate at 

x=3

derivative = derivative.subs(x, 3)

subs(x, 3) replaces 

x with 3  

Print the Result

print(derivative)

The output will be:

55
