Question

Submit as a script file spirals3d.m Create a single graph of the 3-D parametric equations below. Submit this as a .m script file of commands, not as a function. Use t values from 0 through 6pi with increments of 0.1. Put a grid on your graph and label your axes (x, y and z will do for labels).

x = sqrt((t) sin(2t)),

y = sqrt((t) cos(2t)),

z = 0.5t

Your single graph (which is actually two graphs in the same window) should look like this:

Explanation / Answer

t=0:0.1:6*pi;

x=sqrt(t.*sin(2*t));

y=sqrt(t.*cos(2*t));

z=0.5*t;

subplot(1,2,1)

plot3(x,y,z)

xlabel('x')

ylabel('y')

zlabel('z')

grid on

subplot(1,2,2)

plot(x,y)

xlabel('x')

ylabel('y')

grid on
