Answer:
nπ /11
Step-by-step explanation:
To find the discontinuities of the function, we have to find the points where it is undefined.
Now

therefore, the function is undefined where

because then
![8\cdot(1)/(\sin11x)=8\cdot(1)/(0)=\text{undefined}]()
The sine function is zero wherever the angle is a multiple of pi:

solving for x gives

which is our answer!
