In fact, using the conventional coordinates where is the polar angle and is the azimutal angle, they always have a term

The direction is to estimate A, we have thus to integrate on that in the question is CAPITALIZED and we have to choose the interval

Remember that if the charge is moving towards the wire its velocity vector would be negative. tree removal   joshuaprice153 20190809 02:42:01  I had found that the information is very helpful. Thatâ€™s a awesome article you posted.I will come back to read some more. towing service   Giubenez 20141022 02:42:06  The only way to solve this problem is to remember the first Spherical Harmonics, or, at least, their dependence to .

The integration is over all possible values of . Since the given function is periodic, you only need to integrate over the period, which is .

The con dition of normalization goes as
\int{psi}dv=1 in which case theta coordinate should aso be taken care of and wich will result in an extra 2.
The result should be \frac{1}{2\sqrt{pi}}

The official solution is essentially correct, though I think it's better to think of the normalization as <>=1, you get the conjugation for free.

They do not specify a theta dependence for the wave function so you can assume it is only a function of phi. Normalize the given function.
