Use Newton's method to find the parameter values t$1$ and t$2$ where the curve intersects the line y $=1\mathrm{.}2.$ USE the provided MATLAB functions splineeval.m and diffsplineeval.m$.$ Give a short justi cation for your choice of initial guess for each of the two intersections. Your report should contain your MATLAB commands and the computed parameter values t$1,$ t$2$ with $8$ significant digits.
