period#=216^@#

Explanation:

The period of a sinusoidal function can be calculated with the formula:

period#=360^@/|k|#

In this case, since #k=5/3#, we can substitute this value into the following equation to find the period:

period#=360^@/|k|#

period#=360^@/|5/3|#

period#=216^@#

#:.#, the period is #216^@#.
