I have the following questions. I have a few more on using Legendre polynomials but I will read 4.3 first before asking
a) what does selecting

independently
with P(x) mean? In earlier homework, we selected the points at random from [-1,1] which was clear to me - I used a random function with min = -1 and max = +1 but I am not clear what to do with P(x)
b)

is clear since it is f(

). Should we generate random numbers for each

? If so, what are the min and max values for the random numbers?
Thank you!
