Answer to Question #43129 in MatLAB | Mathematica | MathCAD | Maple for Yin Yin Moe

Question

Create a vector of x values from 0 to 20π, with a spacing of π / 100, where
y = x ∙ sin(x)
z = x ∙ cos(x)
12. Create an x-y plot of x and y.
13. Create a polar plot of x and y.
14. Create a three-dimensional line plot of x,y, and z. Be sure to add a title and lables.
15. Figure out how to adjust your input to plot3 in Problem 14, to create a graph that looks like a tornado.

Answer 1

x = 0:pi/100:20*pi;
y = x.*sin(x);
z = x.*cos(x);
plot(x,y);
pause(3);
polar(x, y);
pause(3);
plot3(y,z,x);
xlabel('Axis for Y variable');
ylabel('Axis for Z variable');
zlabel('Axis for X variable');
title('Tornado');
