    Quick question about linearization using the small angle method

    I see, thank you. I was just looking at the method of linearizing where you take the partial derivative of every variable and noticed that you wouldn't have any constants left doing this.

    Quick question about linearization using the small angle method

    Hey guys, when you're linearizing a function that has a constant, what do you do to it? An example would be y = x^2 + 3, would you just linearize it using its derivative and get rid of the constant?

    Linearizing a system of equations?

    I see, a followup question on linearization I have is how would I treat the velocities? An example would be w_z'. In this equation, when I take the partial derivative with respect to phi, how would I treat w_x, since it is the first derivative of phi?

    Linearizing a system of equations?

    The voltage hint is that since we are only operating in the z-axis they will always have the same value. I think it has to do with converting it to state space representation, not I'm certain we use small angle approximations, he said we would prior to getting the assignment. What confuses me...

    Linearizing a system of equations?

    Homework Statement So these are the equations of motion for a quad-copter. I am supposed to create a MATLAB model for the z-axis. In order to do this I have to linearize the equations around these points, and arrange them in state space representation. Homework Equations As above The...

    Electrostatics: calculating the E-field of a line charge

    Here. Would this be the correct integral?

    Electrostatics: calculating the E-field of a line charge

    Yes, I guess I should preface this by saying I'm currently doing this for my electromagnetics class as a third year engineering major, so I do have plenty of experience with vector calculus. That being said I probably worded my previous question poorly haha. In other words, in order to find the...

    Electrostatics: calculating the E-field of a line charge

    My current rendition of the solution looks something like this(going to try my hand at the correct formatting, if this looks gross I'll edit): E = 1/(4piε) * \int l_l/(r^2 +z^2) \, dz' So from what I gather I;m going to do the integral twice, but with each one modified to isolate the r and z...

    Electrostatics: calculating the E-field of a line charge

    It's an arbitrary point in cylindrical coordinates.

    Electrostatics: calculating the E-field of a line charge

    Yeah I noticed shortly after posting this that I didn't even have the correct amount of integrals for the differentials. Wouldn't that just make the integral (on mobile so I apologize for bad formatting): 1/(4piEr^2)* int(charge density*dz) over the length of the line? Don't I have to...

    Hey guys, could anyone tell me if set up this integral correctly? Thanks in advanced!

    Textbook recommendations on semiconductor fabrication?

    Hey friends, taking a class on semiconductor fabrication and my professor both can't teach and doesn't use a textbook. I'm going to take it upon myself to learn the material independently, so can anyone recommend a good textbook on the subject? Thanks in advance!

    Revisiting Mathematical Concepts in Physics: Is It Worth the Frustration?

    And while I'm on my mini tirade I want to add that trying to find shortcuts around learning math is an insult to the rest of us who spent countless sleepless nights studying hours of material, hundreds of cups of coffee, literal tears to get through out education.

    Revisiting Mathematical Concepts in Physics: Is It Worth the Frustration?

    Honestly if you can't handle the criticism you've been given you wouldn't be able to handle the trials of learning anything. These people want to help you but you refuse it. You need to realize that becoming good at anything is hard, be it STEM, music, writing, or art. Anything worth pursuing is...
