Helo!
Please see attached file.
I have an piecewise linear function.
How can I program Marhcad to calculate where the graph intersects the abscisa?
For this case I have two values as you can see from the graph.
Please help
That is the only value. The graph also appears to cross at 1, but that connecting line should really not be there. The function is discontinuous, and jumps from a positive value to a negative value.
Yes thats correct, but how to detect this change in sign (+ --> - ) so that it also appears as a second solution?
Basicly at this point "graph" goes from +5 to -1
Maybe to change the piecewise linear function input somehow...but how?
Well, then the second "solution" would be 1. You don't need to solve anything to get that though, because it's how you defined the function.
