Hey guys,
I'n new to PTC . Trying to get away with solving equations. I'm having some issues heres, if someone could help that would be very appreciated .
I want to solve the following equation :
Y=x(R2/(R1+R2)
Where :
Y=0.8,X=12,R1=10
R2=Unknown
So I type the following on mathcad :
R1:= 10
X:=12
Y:=0.8
Y=x(R2/(R1+R2) => Solve,R2
Unfortunately it keeps saying that R2 is undefined . Does someone know what's going on here ?
Thanks a lot guys.
Solved! Go to Solution.
Always attach your worksheet, too. Not just the pic.
You have to use the boolean/comparison "equal to" and not the "normal" one which is for numeric evaluation.
As you are only after a numeric result you may also use a numeric solve block or the numeric "root" function instead of the symbolic "solve".

You are welcome!
BTW, "24-Ruby IV" is an expression of a rather stupid and peculiar ranking system which is implemented here in the forum, its not my nickname (like yours is not "2-Guest") 😉
