Angular wave function of ${\mathrm{P}}_{\mathrm{x}}$ orbital is : ( Given : $\mathrm{\theta }$ is angle from z-axis).

Angular wave function of ${\mathrm{P}}_{\mathrm{x}}$ orbital is when the angle is from z-axis can be given as;

$\begin{array}{r}{\left(\frac{3}{4\pi }\right)}^{1/2}\sin \theta \cos \varphi \end{array}$.
