what are the spherical coordinates What are the spherical coordinates of the point whose rectangular coordinates are 
(3 ,   1  , 4 ) ?
I got that =sqrt26 but I could not find the values for the others 

In terms of Cartesian:
Cylindrical coordinates:
\begin{eqnarray}
\rho&=&\sqrt{x^2+y^2}\\
\theta&=&\tan^{-1}{\frac{y}{x}}\\
z&=&z
\end{eqnarray}
Spherical coordinates:
\begin{eqnarray}
r&=&\sqrt{x^2+y^2+z^2}\\
\theta&=&\cos^{-1}{\frac{z}{\sqrt{x^2+y^2+z^2}}}\\
\phi&=&\tan^{-1}{\frac{y}{x}}
\end{eqnarray}
