Hello people of physics I am writing a paper for an undergraduate quantum mechanics course (my second quantum course) on the following topic The role of entanglement in quantum computing Just wondering if somebody could recommend a good paper or a good book on this topic. Any suggestions...

Its an assignment question, but I'm also curious if there is a generalized technique for approaching this type of problem

No this won't work either, you will end up with a function that has non integer cos terms Unless I misread what you were saying

Yes, I've tried almost every standard substitution. I don't think this will solve the problem since the amplitude varies with x. Plotting the function in maple reveals that it doesn't have the form of a simple cosine function

Yes, it equals cosx but the frequency is still different so you can't easily combine the two terms. I don't think there is any way of combining the two terms into one simple function. The solution must have an amplitude that oscillates as a function of x; like a form: Asin(Bx+C)sin(Dx+E) Not...

Hi there I was wondering if there is a simple way to solve for the roots of a complicated summation of trig functions that can't be combined with any simple identities. I have an equation of the form: 0 = sin(8x-arctan(4/3))+3.2sin(16x+pi/2) where the two sines have different amplitudes...
