how do i write the code to plot this ?

can someone please help write the code to plot this figure

I have a comment that is unrelated to this thread:

Please don't delete your questions without any response and post a similar one. That makes it difficult to keep track of the questions. The only thing it achieves it that it annoys contributors who feel they are spending time on something useless.

will i didn't delete it someone did it and they said that I'm actually trying to make people do my homework for me which is just insane

[Rik]

My activity feed disagrees:

One other question was closed, which is a very different thing. And it isn't insane to conclude from that question that you wanted others to do your project for you, since you didn't ask a specific question. You can find guidelines for posting homework on this forum here.

Something like:

t=0:.1:40;
x=cos(t);
y=sin(t);
z=t;
plot3(x,y,z);

i thought of this too but the problem is that they dont look the same see

[David Hill]

You should be able to figure it out from here.

[Ahmad Farghaly]

t=0:0.1:31.5;
x=sin(t);
y=cos(t);
z=t;
plot3(x,y,z);

is this it? i mean the figuers look the same but i'm not sure because i do not know how to add the layout grid to compar them together
