How can i ploting 3 function with 2 variables?

Hi i have 3 function like this

x1=(5+sin(w1*t))*cos(w2*t), x2=(5+sin(w1*t))*sin(w2*t), x3=cos(w1*t)

the t variable is not important for me but w1 and w2 is change like this

w1/w2=4, w1/w2=0.25, w1/w2=5 ....

i want to plot this 3 function in 3D but i cant!!!!!!

Surface plot or plot the points?

[mostafa]

plot the points but connect them with line

[Patrik Ek]

ok try plot3

[mostafa]

this is what i do

if true
  %  t = 0:20:2*pi
w2=0:20
w1=4*w2
m=w1*t
n=w2*t
x1=(5+sin(m)).*cos(n)
x2=(5+sin(m)).*sin(n)
x3=cos(m)
plot3(x1,x2,x3)
end

bu i didnt get the correct ans

Ok, the largest error is that t is always equal to 0. Why you plot a point on the same place 20 times: but changing t to t = 1 and looking at the graph, makes still no sense to me. It may do for you, but if you do not mind, what are you trying to plot. You should check the help, but what you are doing is not plotting 3 grahps in 3d, but plotting one graph with the coordinate x1, x2, x3 (x,y,z). You said t is not important, but why is it used then?

thank u for your respond Patrik. i meant that the t variable is not important for me not the whole. i think by saying that i need the points i made a mistake. these functions should give me curve. its about chaos and non linearity dynamics. by the way the t variable should grow not being a constant.

Ok this seems to give some chaotic pattern.

t = 0:0.01:2*pi;
w2=linspace(0,20,length(t));
w1=4*w2;
m=w1.*t;
n=w2.*t;
x1=(5+sin(m)).*cos(n);
x2=(5+sin(m)).*sin(n);
x3=cos(m);
plot3(x1,x2,x3);

Thanks a lot!!!!!
