Hi professor, on pg. 8, 2nd example, it reads: "Similarly the function f(x):= sin (2*Pi*i*n*x)." Shouldn't it be written without i, since Sin (x) takes real valued x?
Note, I noticed that there is another Chris in the class that has posted on the bonus points. So i will be Chris#2, so i am the same Chris (email chris314@ucla.edu) that gave the "for all x" corrections on pg. 2)
