Default Re: validation exercises, unclear about non-linear transformation functions

thanks,
Dorian.
\phi_0 through \phi_7 correspond to the coordinates given in the preamble to Problem 1, namely 1,x_1, \cdots, |x_1+x_2|. The full transformation of \phi_0 through \phi_k for a given values of k would be given by the vector \phi_0,\phi_1,\cdots,\phi_k.
