Whitney goes into Rodger’s Pizza-Toy store and buys a toy for $14. She gives Rodger a $20 bill. Rodger doesn't have any change,

so he takes the $20 bill across the street to Kevin, the clerk in Plato’s Gym. Plato trades Rodger’s $20 bill for twenty $1 bills. Rodger comes back and gives Whitney $6 in change. Whitney takes the toy and the $6 chance and leaves town forever. Half an hour later Plato comes over to Rodger’s gym, furious. He has discovered that the $20 bill he gave him is counterfeit. Rodger, gives Plato a genuine $20 bill he has in the till from an earlier sale.

Find the area of the surface correct to four decimal places by expressing the area in terms of a single integral and using your
love history [14]

If we substitute x=r\cos\theta and y=r\sin\theta, we get r^2=x^2+y^2, so that

z=\cos(x^2+y^2)=\cos(r^2)

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

Consider the function f(t)=\cos(t^2) defined over 0\le t\le1. Revolve the curve C described by f(t) about the line t=0. The area of the surface obtained in this way is then

\displaystyle2\pi\int_C\mathrm dS=2\pi\int_0^1\sqrt{1+f'(t)^2}\,\mathrm dt

=\displaystyle2\pi\int_0^1\sqrt{1+(-2t\sin(t^2))^2}\,\mathrm dt

=\displaystyle2\pi\int_0^1\sqrt{1+4t^2\sin^2(t^2)}\,\mathrm dt\approx7.4144
