Example

Consider the following functions

f(x)=3x1

g(x)=5x+3

with inner product defined by f,g=10f(x)g(x)dx.

Question 5

What is the norm of f(x) in this space?

(Hint: you can use sympy.integrate to compute the integral)

Question 6

What is the norm of g(x) in this space?

Question 7

What is the inner product of f(x) and g(x) in this space?
