A computer algebra system is recommended. A manufacturer of corrugated metal roofing wants to produce panels that are 48 in. wide and 2 in. high by processing at sheets of metal, as shown in the figure. -!l The profile of the roofing takes the shape of a sine wave and the sine curve has the equation y = sin( 2in 'l (D 'X ). Find the width w (in inches) of a at metal sheet that is 12 needed to make a 48-inch panel. (Numerically evaluate the integral correct to two decimal places.) 49.03 x in. Need Help? The figure shows a telephone wire hanging between two poles at x = 35 and x = 35.
