33. Your metal fabrication company is bidding for a contract to make
sheets of corrugated iron roofing like the one shown here. The
cross-sections of the corrugated sheets are to conform to the curve
Зп
y = sin x, 0<x< 20 in.

If the roofing is to be stamped from flat sheets by a process that
does not stretch the material, how wide should the original mate-
rial be? To find out, use numerical integration to approximate the
length of the sine curve to two decimal places.
