Extracted text: 2. Suppose x takes on the values x = 1,1.2, 1.4, ..., 5. Use MATLAB to compute the array y that results from the function y = 7sin(4x). Use MATLAB to determine how many elements are in the array y and the value of the third element in the array y. 3. Use MATLAB to plot the functions u = 2log10(60x + 1) and v = 3cos(6x) in the same axes (note: do use the hold command) over the interval 0 < x="">< 2.="" properly="" label="" the="" plot="" and="" each="" curve.="" the="" variables="" u="" and="" v="" represent="" speed="" in="" kilometres="" per="" hour;="" the="" valuable="" x="" represents="" distance="" in="">
