I need this done in Matlab language.

Winter 2019 Laurentian University 2. Consider the system of equations 412-53-10 It can be described as A.X-b, where 3-2 3 25 17 2 13 (a) Solve the system using the | notation. (b) Construct the extended matrix of the system, which consists of A plus an extra column representing the vector b, and then apply the rref function. Then extract the solution vector from the result. 3. Define in Matlab a mctionwhich computes the value (a) 10 sin(a) +2 -+ 7.cos(a). Make sure to define using it using the dotted versions of the operations, so that you can apply the result to vectors. (a) Construct a vector t of values from -6 to 6 with a step of 0.1. (b) Construct the vector of values y. (c) Plot the function on the given interval using the vectors above. (d) Plot in the same window the function g(x) -0. To do that, you can just define an anonymous function which outputs 0, or just graph the segment with endpoints (-6, 0) and (6,0). (e) Note that the graph crosses the r-axis four times. This means that the equation f(x)0 has four solutions in that interval. Use the tzero function to find all of these roots. For the second parameter of fzero, input a number which is close to the root that you want to find. Use the plot to guess a first approximation. (f) Verify the roots found by applying the function and see if you get o, or a very close approximation
