# Coding challenge

Write some code that will generate a random number $r$, between 0 and $2\pi$, then compute $sin(r)+k$, where $k$ is some constant that you can choose (10, 5, -5.323, etc.). Something like
k=3
r=2.0*math.pi*math.random()
y=k+sin(r)

should do it. Generate 1,000 of these y's and find the average of them. Can you explain your result? What about $k+\sin(2r)$? $k+\sin(100r)$?
