    Mathematica Scaling Axes in Mathematica for ParametricPlot

    Hi, Am plotting a graph and need to scale the axes so that i can take my range of 'x'-axis values from -1 to infinity. I shall provide script, but i am using the ParametricPlot command. ParametricPlot[tab2, {up, -1 + 10^-7, 10}, AxesLabel -> {"\[Rho]", "u'"}, PlotRange -> {{-1, 2}...

    Solutions for x<0: Konig's Method

    So \sqrt{-x}, x<0 will give a positive answer. Although I am not sure what to do about the x^{\frac{3}{2}} part of the equation. The answer should have natural logs and some x terms. the solution of \frac{dy}{dx} = \frac{1}{x^{\frac{3}{2}} (1-x)^2} gives a similar answer to what i need...

    Solutions for x<0: Konig's Method

    Hi, I have solved a differential equation (1) for x, where i think is a real variable. (1) \frac{dy}{dx} = \frac{1}{x^{\frac{3}{2}} (1+x)^2} And get a solution y(x) = \frac{2}{\sqrt{x}} - \frac{\sqrt{x}}{(1+x)} - 3 \arctan{\sqrt{x}} Now, i want to find solutions for x<0, and i have...

    Solve First Order Homogeneous ODE | Constants a and b | Help Needed!

    thanks for the response Jackmell, Am currently working on it, though keep making maths errors which are slowing me down. I agree it would be a good idea to compare, thanks for the tip. The problem is part of a project, so yea the problems not meant to be easy. demoralising thing...

    Solve First Order Homogeneous ODE | Constants a and b | Help Needed!

    Hi, need help solving a first order homogeneous ODE. y'(x)-(a/x)y = b/(x(1+x)^2) Here a and b are some constants. Need to solve this for y. My attempts so far have been to use But this means solving ∫ x^(-a)/(x(1+x)^2) dx which has solutions in terms of Gauss hyper-geometric functions...

    Photoelectric effect minimum frequency

    So it still can, but it is just unlikely? What happens when you have many energy levels for the electron to go, so that when the photon hits it it can exist at a higher energy level, and then is hit by another photon before it becomes de-excited? In The case of no higher energy levels...
