Question 1: Gauss elimination and LU Factorization Based on your student ID 19-0351 (ab-cdef) ax + dx2 + exz = f a) Create 3 equations based on your team's student ID. Use Octave and gauss elimination to solve them. Make a screenshot of the code and the result. d e fi b) Create matrix A = d2 ez 12 use Octave to find the upper triangular matrix U and a dz ez f3 permuted lower triangular matrix L. Make a screenshot of the code and the result. Question 2: Numerical integration Consider SA sin(Vx+B)evo Vx dx. Use Octave to calculate the value of this integral. A and B are constant numbers. Let Gutech ID of your team leader 19-0351(ab-cdef): then A = (c + d) = 3 and B = (a + b + d) = 13 Note A and B can't be zero (if come back to the lecturer earlier) Make a screenshot of the code and the result. Question 3: Numerical differentiation Find the derivation for the product (3x2 + 6x + 9)(x2 + 2x). Make a screenshot of the code and the result. Plot the original function and the derivation in one graph. Provide a legend for the plot
