I have to measure a distance between two points. I have to see where the solution across some values quite small, like 0.01. In other words, there should be the first point which is like (x(150), 0.01) at t=150 and the second one should be (x(200), 0.01) at t=200. Distance should be equal (x(200)-x(150)) because y-values are the same.
My problem is that how can I store/ calculate the x(150) and x(200) places when the time reaches to t=150 and t=200, respectively?
I will be very glad if someone can answer my question.
Many thanks in advance.
