[QUOTE="Ray Vickson, post: 5028184, member: 330118"] What are you trying to do? If you know the values of a, b, x, y you can plot a graph of y over a range of t values. If you are trying to find the maximum and minimum values of y, you have a Calculus problem whose solution would (generally) require numerical solution methods---there would no universal "formula" you could use the find the desired values. If you are trying to determine whether y(t) is periodic--and to find the period if it is---there would be still other calculations you would need to make. So, what you should do depends on what you are attempting to achieve. [/QUOTE]
