Initialize
x = x + dx y= y + dy dx = dx  k*y dy = dy  k*x PLOT (x,y) Keep taking the medicine TRUST ME D

yeah I tried doing the ploth version it still needs a copy and paste plus some resizing lol

Here's a crude technique that works for that case:
Code:
ploth(x=5,5,sqrt(25x^2)*(1)^random(2),64)

If the threads were merged, then OP's post #8 and my post #10 should be deleted. And this current post too. Thanks.

how could you ploth a rectwindow with multiple curves/lines in it, I know how to make rectwindows and I know how write to a rectwindow I don't see how to ploth the results.
edit: think I found it (plotrecthraw) but don't see how to get it working,okay got it working but not exactly what I wanted by the looks of it. Last fiddled with by science_man_88 on 20120829 at 21:53

Why my solution in post #9 is not good for you?
Pari's "ploth" is a very clever function, it can plot vectors of functions, even recursion, in many different parametric ways. Try playing with the last "1", make it "0" or none. Or RTFM, it has good examples. If you keep that fixed idea of using the sqrt(blabla) function, why not try: ploth(x=5,5,[sqrt(25x^2),sqrt(25x^2)]) edit: try this for a start: ploth(x=5,5,[x^3/25,5*sin(x),x*sin(20*x)/51.1*x,sqrt(25x^2),sqrt(25x^2)]) Last fiddled with by LaurV on 20120830 at 03:14

plotinit() initializes a rectwindow plotrecth() writes data to a rectwindow plotclip() clips the data to the correct size. but I can't figure out which one draws the results. Last fiddled with by science_man_88 on 20120831 at 12:26

A simple graph of a circle in Pari:
Code:
ploth(X=0,2*Pi,[sin(X),cos(X)], "Parametric")
