3π TT 4 4 1. Suppose that to build a 3×3 matrix in which the first column contains the sine of the elements between and 27, the second column contains the sine of the elements between and 37, the third column contains the sine of the elements between and Two spacing are required between the elements. You are requested to find the determinant and the inverse of the aforementioned matrix (Hint: Use linspace(a,b,n) to build three rows and transpose of a matrix to find the columns of the aforementioned matrix) a) Sketch the flow diagram b) Write the MATLAB Code on the answer sheet to construct this matrix, to find the determinant and the inverse of this matrix. c) Add explanation (comment) for each line of this MATLAB Code. d) Run the m-script and show the screenshots on your answer sheet by using the "print screen" button on the keyboard. e) Discuss what it can be said about the matrix in terms of its determinant and in terms of its inverse. 2.
