Arrange the periods for the following in the ascending order

$$\begin{gathered} A)\tan \left(2x-7\right), B)\sin x\cos x, \\ C)\sin 3x+\cos 3x D){\sin }^{3}x-{\cos }^{3}x \end{gathered}$$

 

$$\begin{gathered} period of \tan (2x-7)=\frac{\mathrm{\pi }}{2} \\ \sin x\cos x=\frac{1}{2}\sin 2x\Rightarrow period of \sin x\cos x is \frac{2\mathrm{\pi }}{2}=\mathrm{\pi } \\ \mathrm{Period} \mathrm{of} \sin 3\mathrm{x}+\cos 3\mathrm{x} \mathrm{is} \frac{2\mathrm{\pi }}{3} \\ \mathrm{Period} \mathrm{of} {\sin }^3\mathrm{x}-{\cos }^3\mathrm{x} \mathrm{is} 2\mathrm{\pi } \\ \mathrm{ascending} \mathrm{order} \mathrm{is} \mathrm{A},\mathrm{C},\mathrm{B},\mathrm{D} \end{gathered}$$
