Hidemons Posted September 2, 2009 Share Posted September 2, 2009 I've always had a problem understanding the concept of equations that do not simply start with Y(x) = ...... This one for example: V(x+1) = V(x)+(g-(Cd/m)*v(x)^2)(ti+1-ti) is one that I have to make into a plot for this program called Matlab. (for computing stuff) Can someone explain this equation to me or enlighten me on the subject. How should I simplify this to make it more understandable?

the tree Posted September 2, 2009 Share Posted September 2, 2009 Recurrence equations involve about as many techniques as differential equations. But you shouldn't need an analytic solution just for a plot of the system. A simple WHILE loop should generate a big enough set for an interesting plot.
