We have the following:
[tex]\begin{gathered} y=-3cos\mleft(x+2\pi\mright)\rightarrow P=2\pi \\ y=\frac{2}{3}cot\mleft(\frac{x}{4}\mright)+6\rightarrow P=4\pi \\ y=-\frac{1}{2}tan\mleft(\frac{5x}{6}+\pi\mright)\rightarrow P=\frac{6\pi}{5} \\ y=5csc\mleft(3x\mright)+6\rightarrow P=\frac{2\pi}{3} \\ y=y=-10sin\mleft(\frac{x}{5}-2\pi\mright)\rightarrow P=10\pi \end{gathered}[/tex]
therefore, in decresing order would be:
