$\vec{F}(x,y,z) = M(x,y,z)\ \vec{i} + N(x,y,z)\ \vec{j} + P(x,y,z)\ \vec{k}$

$f(r,\theta,\phi,a) = \frac{|Sin(a\; \phi)|}{r}$

$f(r,\theta,\phi,a) = |\frac{Cos(\frac{\pi}{2}\; Cos(a\; \phi))}{Sin(a\; \phi)\; r}|$

$f(x,y,z,a) = \frac{|Sin(a\; ArcCot(\frac{z}{\sqrt{x^2+y^2}}))|}{\sqrt{x^2+y^2+z^2}}$

$f(x,y,z,1) = \frac{|\frac{\sqrt{x^2+y^2}}{\sqrt{1+\frac{x^2+y^2}{z^2}}\; z}|}{\sqrt{x^2+y^2+z^2}}$
