    Determining graphical set of solutions for complex numbers

    Homework Statement So we have been doing complex numbers for about 2 weeks and there is this one equation I just can't solve. It's about showing the set of solutions in graphical form (on "coordinate" system with the imaginary and the real axis). So here is the equation: Homework Equations...

    MATLAB How to use a suitable color bar?

    I have a picture which shows the magnitude of some value in terms of color, like this one: https://www.dropbox.com/s/yoh0n9cqftvrtlz/bar.jpg?dl=0 The higher the magnitude, the more it looks red. However there are only a few points at the edge has very high values and most of the points have...

    Determination of Rydberg Constant via Graphical Method

    Homework Statement Not sure if this belongs in the 'Advanced' section so apologies if it does not. I am using a monochromator to measure spectrum lines from a rubidium lamp. From the data (wavelength of spectral lines plus transition number 'n') I am asked to use a graphical method to...

    LP objective function with unknown parameters

    Hi All, I am struggling with minimization(maximization) problems which needs to be solved graphically but they have unknown parameter in objective function: For example: f = 2x_1 + \lambda x_2(min) for conditions: -x_1 + x_2 \leq 3 x_1 + 2x_2 \leq 12 3x_1 -x_2 \leq 15 x_i \geq 0 More than...

    Graphical method to calculate power

    Homework Statement I have been asked to show a graphical, more accurate method to calculate power used when running up a flight of stairs. The method I have used previously is measuring the height of the stairs, recording my weight in Newtons, timing how long it takes to run from the bottom to...

    Vector 2B - Vector A (graphical method)

    Homework Statement Vector A is 4.00 units and 40* below x-axis. Vector B is 3.00 units and 25* below -x-axis. Use the graphical method (only ruler and protractor) to find Vector 2B - Vector A. I have to find the magnitude and direction. When I did it I got 8.5 and East, but I'm not sure...
