making a graph for a projectile trajectori

[spedersen]

Hi there.

i am trying to graph a projectiles trajectori with air ressistance.
I have been trying to program a while loop, which for a small increment in time will figure out the X and Y coordinates of the projectile.
I think i have done that part correctly, but keep in mind i am a rookie in mathcad.
My biggest problem is thus after the loop has come to an end, how do I store the data points and graph them?
i have attached my mathcad document, any hints,points or solutions would be much appreciated.

I've changed your program so that it builds an array of your calculation as it goes.

Recognize that there are lots better ways to do this in Mathcad; you can create functions and use units.

Search this  web site, there have been a lot of submissions on trajectories.

Here's another way, calculating the individual vectors within the program.  It's a lot messier than Fred' way, but is purely a method demo.  It's also (as shown) often useful to include a simpler model to test the structure of a program.
