The unanimous Declaration of the thirteen united States of America

"When in the Course of human events it becomes necessary for one people to dissolve the political bands which have connected them with another and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation."

A steady wind blows a kite due west. the kite's height above ground from horizontal position x = 0 to x = 120 ft is given by y =

professor190 [17]

The derivative of the vertical position is
.. y' = 2/40*(x -50)
so the integral that gives the length of the curve the kite traveled is
$distance= \int\limits^{120}_{0} {\sqrt{1+(\frac{1}{20}(x-50))^{2}} \, dx$

It is convenient to let a graphing calculator compute this integral numerically. If you want to do it analytically, a table of integrals can be handy. The indefinite integral is
$\frac{x-50}{40} \sqrt{(x-50)^{2}+400} +10 arcsinh(\frac{x-50}{20})$
This evaluates to
$\frac{1}{2}(25 \sqrt{29} +35 \sqrt{53}) +10(arcsinh( \frac{5}{2}) +arcsinh( \frac{7}{2})) \approx 230.8$ feet
