Section 1 - Solve the following problems 1. Given the following system of simultaneous equations: 2x + 4y +62 = 2 x + 3y + 5z = 4 9y+112 = 6 a. Please find the inverse of your A matrix from (a) by hand showing all steps (20 points). b. Using your results from (a), please solve for x, y, and z (5 points). 2. Given the following information: 2.5 2 1.5 t(x) = (8n(x) = cos(x)). 2 0.5 0 -0.5 1 -1.5 7 where f(x) (sin (x)+C03(x)) - 2 a. Approximate the root on the left using the false position method. Use an initial subrange of [0,4) and use 3 iterations (15 points) b. Approximate the root on the right using the Newton Raphson method. Use 5.50 as your initial guess and use a tolerance of 0.001 (15 points). Section 1 - Solve the following problems 1.
