![]() ![]() Mathematica says my function doesn't have a real part at all. I programmed the pertaining variables in many different ways and tried a command of the form Plot ], but I keep getting an empty graph. This is a little too ambitious for me, so I'm just looking to plot this thing for a fixed phase angle omega x t, so that I can worry about finding the graph of u as a function of zeta only. When the real part of the equation is plotted for a fixed unsteady Reynolds number (capital omega) = 3.0 at different phase angles omega*t, starting from 0 and then increasing by 90º each time, I'm supposed to find something like this, So far the most often used is the classical fourth-order Runge-Kutta formula, which has a certain sleekness of organization about it: (1) y n + 1 y n + h 6 ( k 1 + 2 k 2 + 2 k 3 + k 4), where k 1 f n f ( x n, y n), k 2 f ( x n + h 2, y n + h 2 k 1), k 3 f ( x n + h 2, y n + h 2 k 2), k 4 f ( x n + h, y n + h k 3). Mathematica has no equivalent functions for realpart and imagpart known from the Maxima, which operate on expressions and complex numbers (or I dont know about. J0, of course, is a Bessel function of the first kind and order zero. Where r is the radial distance from the tube axis, t is the time, capital lambda is a function of the unsteady Reynolds number capital omega,Īnd zeta is a normalized radial coordinate, The normalized equation that I need to plot is this one, Okay, that's an euphemism, what I meant is "I suck at it and need help." I'm struggling to plot the real part of the velocity profile for pulsatile flow in a rigid tube. I just got started in Mathematica, so my knowledge regarding the software is pretty limited.

(1) is a 2×2 matrix and x ( t) is a 2-dimensional column vector, this case is called planar, and we can take advatange of this to visualize the situation. Using Mathematica, I want to separate the real and imaginary parts of a non-numeric expression. (1) x A x, where x d x / d t, and A is a square matrix.
