Solve equations witch contains absolute values
Solve equations witch contains absolute values
(OP)
Hi
(I apologise for my bad english!)
I have a question about mathcad. I have a equation loking something like this:
f(x)=N/A+M*(x-y)/W
witch I like to solve for f(x)=0
with other words, I like to find the x for witch f=0
The problem is that the term (x-y) should be the absolute value and to me it looks like mathcad cant solv the equation using f solve,x-> when it contains absolute values
I then tried to rewrite the term like this:
squarrot( (x-y)^2)
witch of corse is the same but I thought this way to write it maight help but NOP it dident. Matchad was unable to solve the equation so my question is:
How do i get Mathcad to solve equations witch contains absolute values?

Then it is easy, even if Mathcad can't do it.
mod(x-y)=-N/A*W/M
x=y+(N*W/M/A)^2

RE: Solve equations witch contains absolute values
Thanks for quick answers!
Unfortunately I cant tell whether zero, one or two of M, W, A and N will be negative. I guess I have to find another way too get around the problem.
Thanks anyway!
