A manufacturer of corrugated metal roofing wants to produce panels that are a = 60 cm wide and 4 cm thick by processing flat sheets of metal as shown in the figure. The profile of the roofing takes the shape of a sine wave. Verify that the sine curve has equation y = 2 sin(x/15)
and find the width w of a flat metal sheet that is needed to make a 60-cm panel. (Use your calculator to evaluate the integral correct to four significant digits.)

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
