Working on Matlab assignment. I need to plot the function y=cos(x)+e-x and assign the plot to q. i put in the following, but it's not working: syms x figure q=fplot(cos(x)-exp(-x)) What am I doing wrong?

Write Matlab program to plot the functions: f1 = sin(2x)  f2 = 2sin(x)cos(x) Given x = 0:0.01:2pi

Write a MATLAB function, called fixed_point_iteration that inputs a function, g, an initial guess xo, an error tolerance, tol, and a maximum number of iterations, N , and outputs the fixed point of g, obtained using the fixed point iteration, starting with xo- Your function should have an error defined by E = |x,- Xn-1|, and stop when the error is less than the tolerance, or if the number of iterations exceeds N - whichever happens first. Your function header should look something like: | function [c,n,err] = fixed_point_iteration(g,xe, tol,N)

Can you help me program in MATLAB? I want to plot the magnitude of Modified Rodrigues Parameter (MRP) vs theta. I need 2 plots where theta equals (0,pi) and (pi,2*pi). Also, I need the same plots but for the shadow set of MRP vs theta.

Using MATLAB : Please explain the process of how you constructed your code and provide screenshots of the output, pictures and graph

iv) Plot the curve of the function z(t) = t + 3t3 - 7t + 3 in MATLAB. Range of t is from -10 to 10.
