I got it from changing the DE into m^2 + 2m + λ I did the "m" thing because in the previous chapters to solve some equations I would solve the associated homogeneous DE and use the value of m to determine the structure of the general solution. It's the only step I have made and I feel like even...

Homework Statement Find the eigenvalues and the eigenfunctions for x^2y"+2xy'+λy = 0 y(1) = 0, y(e^2) = 0 Homework Equations See problem The Attempt at a Solution My book has one paragraph on this that does not help me. I tried using an auxiliary equation and solving for lambda...

Homework Statement Graph the curves y = (x+4)(x-5) and y = ax+2 for various values of a. For what value a is the area between the two curves a minimum? Homework Equations y = (x+4)(x-5) y = ax+2 The Attempt at a Solution For my attempt I attempted to find the primary equation...

There we go! For some reason it wasn't quite clicking with me...but I definitely got it now, thank you very much :)

So then using those two values for m I would receive two different values for L. I don't see how having those two lengths solved would help me find the distance to the screen at all. I'm sorry I just don't understand how this leads to a solution...

Homework Statement Light of wavelength 460nm falls on two slits spaced .3 mm apart. What is the required distance from the slit to a screen if the spacing between the first and second dark fringes is to be 4mm?Homework Equations dsin(theta)=(m+1/2)lambda where d = .3mm y=4mm lambda = 460nm...
