$$\frac{{\sin }^2\mathrm{x}+{\cos }^2\mathrm{x}}{\mathrm{sinxcosx}}=\mathrm{p}\Rightarrow \mathrm{psinx}=\frac{1}{\mathrm{cosx}}$$$$\frac{1-{\cos }^2\mathrm{x}}{\mathrm{cosx}}=\mathrm{q}$$$$\mathrm{psinx}.{\sin }^2\mathrm{x}=\mathrm{q}$$$${\sin }^3\mathrm{x}=\frac{\mathrm{q}}{\mathrm{p}}$$$$\mathrm{sinx}=\sqrt[3]{\frac{\mathrm{p}}{\mathrm{q}}}$$$$\mathrm{x}=\mathrm{k}\pi \pm {\sin }^{-1}\left(\sqrt[3]{\frac{\mathrm{p}}{\mathrm{q}}}\right)$$
