Section 5.5, Exercise 23: Use the given inner product to compute the length ||1 + 2t|| and the distance d(3 5t, 4 + t).

23. In the space P1 of the polynomials of degree 1, we define the inner product = 1/2(f(0)g(0) + f(1)g(1)) Find an orthonormal basis for this inner product space.

Hi, you don't need to solve 21, please follow the instructions above and solve the length and distance with the given inner product.
