In electromagnetic theory, the magnetic potential
at a point on the axis of a circular coil is given by
where
are constants. Compute
.
I know
u = r tanx, du = r sec^2x dx
r^2 + x^2 = r^2 + r^2 * tan^2 x = r^2 (1 + tan^2 x) = r^2 * sec^2 x
Integration r sec^2 x dx / (r^(3/2) (sec^3 x ) = Integral of 1/sqrt(r) * cos x dx
Further assistance would be helpful thanks
