Re: Problem Static

What did you expect? You have not defined x and y so you cannot expect a numeric result.

You may let Prime evaluate symbolically, though. 15 REPLIES 15

Due to PTC's greed, since you are using Prime version 5, many of us cannot see your problem.  Consider posting a picture version as well.

Werner, why the final answer did not show in "m", what I'm missing here. If you had to solve this problem through vectors would you do the same thing I did?

Re: Problem Static

That is due to your definition. You defined rp as rp:=[x y 0] m. This means that x and y, like 0 are just numbers, without units. I would be rp that contains x m, y m and 0 m.

If you're interested, you might try to find out what happens if you define rp as rp:=[x y 0] and then solve x and y.

Success!

Re: Problem Static

Thanks LucMeekes, but I did not quite understand the answer, rp = [x y 0] m is different from rp = [xm ym 0m]. I used it the way it said and it did not work, could you please give a practical example.
