Also, our definition of the first 4 Legendre polynomials is: 1 Po(x) V2 P1 (x) = V5/2 (1 – 312) P2(1r) = 2 V7/2 P3 (x) (3x – 5x³) 2 Write x2 as a linear combination of the first 4 Legendre polynomials, i.e. write x? = El = 0°c¢Pe and tell me what the values of the cę coefficients. (Spoiler alert: Some of the coefficients are zero. Some aren't.) If you have to do some integrals here, feel free to use Wolfram Alpha or Mathematica to do them. Now do the same for x. What is the projection of x onto the first 4 Legendre polynomials?
