#24 (hint, use difference-of-cubes factoring formula, see Reference Page 1 at the very front of the book)
WEP #25
#26 (hint, use Wolfram Alpha to factor)

#35 On #35-38, when they say "Use continuity", they mean "These functions are continuous where it counts. Use this fact."

#47

QA: is 1/(1+e^(1000x) ) continuous? Explain.
QB: like #25/26, but use (e^x - e^-x)/(e^x + e^-x)
QC: like #25/26, but use: summation (n=1,3,5,... up to 21) ( (1/n)*sin(n*pi*x) )
