Lorenz equation and plots in MathCad 5

as part of a educational project I am required to plot the Lorenz equations in the x-y,z-x, plots.
has anyone an idea how to do this in MathCad 5 as its new to me.
thanks

Are you talking about the chaotic system stability equations? If you want a sensible answer I suggest that you specify the problem a bit better, but, roughly speaking, you need to prepare a vector of results in the complex plane and then do an XY plot of the real vs the imaginary parts of that vector.

Keystrokes are

Im(results[i)@Re(results[i)

Assuming Im and Re are defined (I think they are).

If you post more detail I'll help.

OK, that was a bit cryptic

1) have you done all the tutorials? If not then you will struggle.

2) set up an indexing series, i, for the number of points you want to calculate. In all the rest <something> is a value that you need to decide.

Type i:0;<number of points desired>

3) x[0:<starting value for x>
y[0:<starting value for y>
z[0:<starting value for z>

4) Then solve x,y,z for all the rest of the values

5) Then plot them using

z[i@x[i

and

y[i@x[i
