Problem 13E

In Problems 1–14, find at least the first three nonzero terms in the series expansion about x = 0 for a general solution to the given equation for x > 0. (These are the same equations as in Problems 19–32 of Exercises 8.6.)

Slide 21 Arbitrary axis. Instead of y, it’s r. S is much less than r. Slide 22 Slide 23 Electric field lines are related to dipoles and show the electric field around the dipole. E1 is the electric field and is tangent to 1 and 2. Slide 24 Slide 25 • E dipole to the left with a positive point charge that
