Find the area of the surface correct to four decimal places by expressing the area in terms of a single integral and using your calculator to estimate the integral. the part of the surface z=cos(x^2+y^2) that lies inside the cylinder x^2+y^2=1

If we substitute and , we get , so that

which is independent of , which in turn means the surface can be treated like a surface of revolution.

Consider the function defined over . Revolve the curve described by about the line . The area of the surface obtained in this way is then

care to share were the trapezoid shown is ?
