Question

For the following question, please use symbolic toolbox to compose proper math equation and signal. And use MATLAB graphical functions to show the waveform.

Question)

a)Create a symbol x, and show signal waveform of y=e^(x)sin(20x) over interval from 0 to 3.

b) On the same figure, mark the y value when x takes value from set [0, 0.25, 0.50, 0.75, ..., 3.00].

Answer 1

Matlab Code for the solution clc clear all close all x = linspace (0,3,13); % This creates the x vector at seperation of 0.25 interval. y=(exp (x*1)). *sin (20+x); % This the equation of y-exp(x)*sin(20+x) creates figure (1) plot (x,y) xlabel ('\bf x); ylabel ('bf Amplitude'); title('bf Graphical plot of ex sin (20x) ); grid on figure (2) plot (x,y, "-s', 'MarkerSize',10,. .. MarkerEdgeColor', 'red',. . . MarkerFaceColor',[1 .6 .6]) xlabel ('\bf x; ylabel ('bf Amplitude); title ('\bf Graphical plot of e1x sin(20x) with mark points'); grid on
