Let if and if and
I'm no good at coming up with examples... please help...
a. Give an example of a function f: [0,2] R such that f isn't Riemann integrable on [0,2], but |f| is.
b. Give an example of a function f: [0,2] R such that f isn't Riemann integrable on [0,2], but is.
c. Give an example of two functions f,g : [0,1] R such that f is Riemann integrable on [0,1], but g isn't and fg is Riemann integrable on [0,1].
