Continuity of Products and Quotients - Expii

To prove continuity of products and quotients of functions, some helpful rules are: if f and g are continuous (at a point or on an interval), so is the product f*g (at that point or on that interval); if f and g are continuous and g is nonzero (at a point or on an interval), then the quotient f/g is continuous (at that point or on that interval).
