![]() ![]() also contact me at am having problem in giving the initial guess root. I am really in need of help as I have been trying to solve it on for weeks by now.Īny body can help me. I want to make plot for the real part of ome in the y axis versus wave number K on the x axis. I have pasted the corresponding lines from my Mathematica note book i used to solve the equation. I need help to solve this equation in Mathematica 6į = (ome + I (we)^0.5 k + 4 m^2 oh)*(ome + I (we)^0.5 k) Tanh[ My equation is a dispersion relation which gives the complex wave growth for the corresponding wave number. ![]() I have a problem of finding the real roots of a complex function. But is there a vay I can tell mathematica to find the rest of the roots automatically? I am attaching a plot of the function which shows all the positions of the roots for a given set of parameters.Īs I said I am quite knew to Mathematica so this question might sound silly but any help would be much appreciated. I can use FindRoot and get one root at the time given I chose the proper starting value. The secant method for numerical root finding of the functions consists of the steps, beginning with the two starting values and. I have this single variable function which has many roots and I would like to know how can I find them all. Steps of the secant root finding method for a cubic polynomial. I have managed to work my way through functions and what not (I am still learning) but at the moment I've reached a delicate problem. So much so that I am trying to use it for one of my research projects as an alternative for mathcad which I've been using for many years and with many frustrations. I am new to mathematica but I am very found of the program. I have just created my account here and so this is my first post and I would like to appologise if my question may have been posted by someone else.
