    Undergrad Small angle approximation for (dθ/dt)^2=0

    yes i probably should have listed the equation numbers. im confused on 2.25-2.27

    Undergrad Small angle approximation for (dθ/dt)^2=0

    lol sorry i just changed it in my post! for 22 degree approx what i meant to say was cosθ=1-\frac{θ^{2}}{2} the information i really need is how the heck they did the taylor series expansion with that derivative. i have my old math book and i can see how they got the taylor series for sine...

    Undergrad Small angle approximation for (dθ/dt)^2=0

    Hey guys, I am looking for a textbook that I can cite as a source for a project, for which I am doing the math on. I know that for a 22° approximation sinθ=θ and cosθ=1-\frac{θ^{2}}{2} but for a 5° approximation sinθ=θ but now cosθ=1 and that's all fine and dandy, but I am looking...

    Undergrad Magnetic fields and Permeability

    about permeability. yes anytime a permeable material is placed in a B field it will contain and concentrate the flux through it, because it does provide a path of lower reluctance. However the material in question can only contain a finite amount of flux. magnetic materials have two important...

    Undergrad Magnetic fields and Permeability

    I believe you meant period of oscillation when you were talking about nanoseconds and pico seconds. if the T (period) is >= 1 ns then we have GHZ frequencies, and if T>= 1ps then we have THZ frequencies. an electromagnetic is simply an inductor. for frequencies that high, unless your...

    Undergrad Practical Electronic & Mechanical Skills for Aspiring Experimentalists

    Well this is true, however since I am an undergraduate (just a youngin) my post is geared towards curious undergraduates who would want to do more than just bury themselves in the taylor mechanics book or the griffiths E&M text. and i do know that for particle physics, there is only so much you...

    Undergrad Practical Electronic & Mechanical Skills for Aspiring Experimentalists

    I just thought Id post some of my thoughts on what I feel is needed for undergrad physics majors who are interested in the more practical side of what we are learning in our highly idealized and theoretical coursework. I also would like to point out what tools I think are necessary for people...

    Is Fitzpatrick's Advanced Calculus the Best Book for Multivariable Analysis?

    the Arfken and Weber Mathematical Methods for Physicists should be rigorous enough for you - its the grad level text. Or you could try a book titled "Advanced Engineering Mathematics" physics majors and engineers often take upper division math classes from a book with this such name. however i...
