Write a MATLAB script to evaluate the equation f(x) = 2sinx + cos(x) + 10 for all values of x between -2n and 2n, in steps of 0.2, do solve by vectorization Question 2 Write a MATLAB function to find the distance between points (x1.y1, 21) and (x2, y2, 22) in a three- dimensional Cartesian coordinate system is given by the equation D = (x - x) + ( - Y) + ( - 2) Ask the user to input the values of (x1, y1, 21) and (x2, y2, 22). Question 3 Write a MATLAB program to create a mesh plot, surface plot and contour plot of the function for the interval -0.3 x 0.3 and -0.3m Sys 0.3m, in each case, plot the real part of z versus x and y. (10) 1 t t 2= Question 4 Write a MATLAB script to plot the implementation of Q1, a. Plot the resulting function f(x) using dashed red line. b. Plot the function using stem c. Add title, Axis, legend and grid on the plot.
