 Jul17 asked Approximate solution for the root of a non-linear function Jul17 comment Variation of a simple random walk Would you mind elaborating on that please? For me it is still not clear. For instance, what would the PMF be for finding the particle at position m after n steps? Same as a n/2 walk? And with what probability, 1/2? Thank you in advance. Jul16 asked Variation of a simple random walk Jul16 answered Please find the expectation Jul16 answered Jointly distributed exponential random variables Jul9 comment System of ODEs with a degenerate (?) critical point I have been precisely trying to find some constant of motion by I am not sure how to do this, or of these is some general method for it. Any advice? Jul9 comment System of ODEs with a degenerate (?) critical point Mr. Hundmark, you are right. Changing the value of x0 will change the output. But I have found by numerical solutions that this tends assimptotically to a given value as x0 becomes smaller and smaller. Jul7 comment System of ODEs with a degenerate (?) critical point If you start at (0.0000001,y0,0) then things happen. The main point is how to deal with situations when the critical point does not tell you the equilibrium points exactly. Or perhaps, what is the "category" of this type of problem. I don't even know what to search. Thanks in advance for any help. Jul6 comment System of ODEs with a degenerate (?) critical point Yes. Or, similarly, if I start with y=y0 then what is y at $\infty$.
