the differintial equation given is:
(a) I did part a finding the x as a function of t when a=b
part (B) is what am having trouble with it states;
If a>b, find t as a function of x. { hint use substitution u=(sqrt(b-x))
i tried the substituon i cant seem to simpify my work after sub, is for the left side
-1/2 integral_ sqrt(b-x)du/(a-x)(u^(1/2))
