Answer :
period of sin(ax) or cos(ax) :
[tex]T= \frac{2 \pi }{|a|}[/tex]
period of tan(ax) or cot(ax) :
[tex]T= \frac{\pi }{|a|}[/tex]
[tex]T= \frac{2 \pi }{|3|} = \frac{2}{3} \pi [/tex]
[tex]T= \frac{2 \pi }{|a|}[/tex]
period of tan(ax) or cot(ax) :
[tex]T= \frac{\pi }{|a|}[/tex]
[tex]T= \frac{2 \pi }{|3|} = \frac{2}{3} \pi [/tex]
