I am new to Mathcad,I have been using PTC Mathcad Prime 5 since yesterday.
I have a problem when I use solve and assume for this quadratic equation. All the variables have mm as unit. If I assume mm <> 0 then it works. The answer I am looking for is 233.41847464108950079 mm.
Ps. If I put = it shows the good answer (my bad, I was too frustrated about the if and else thing to try), but why does it show if and else?
Solved! Go to Solution.
The symbolic processor in Mathcad (and Prime) does not know about units, it treats them as unknown variables.
You can write sol to be a function of Lp, Dp1 and Dp2, so instead of sol:=... you write sol(Lp,Dp1,Dp2):=...
Then you can evaluate sol(Lp,Dp1,Dp2)=
to get the answer.
