The period of sin (kt) is 2#pi#/k. Answer: 2#pi#/11.

Explanation:

x = Sin (t) graph is a series of continuous and periodic waves touching x - 1 and x = 1. The values repeat in an interval of 2#pi# for t, since sin (2#pi# + t ) = sin ( t ). Here, the period is shortened to 2#pi#/11 due to scaling of t by 11. .
