Isn't It Obvious?! Traditional Cache

This cache has been archived.

Teebs: Well, this cache got picked up again by the park. I've got it back in my possession and will come up with a new location where it is less likely to be stumbled upon. Look for a new problem to alter the final coords in the next few weeks....

Geocache Description:

In honor of having completed AP Calculus, we are creating this cache. Who ever said there aren't applications of calculus in the real world? The coordinates given will get you in the vicinity of the cache, but you will need to solve a series of calculus equations to get the coordinates of the actual cache. This cache is dedicated to Uncle Hector, who has taught us to take it to the limit.

The coordinates of the final cache are N 45 3A.BCD, W 122 5E.FGH

 

A) The integral of 1/(x^2) evaluated from one to infinity = A

 

B) 6 times the integral of tan(x)sec^2(x) evaluated from zero to pi over four = B

 

C) Find the area of the region bounded by the curve y equals x times e to the negative x and the x-axis from x=0 to x=3. Multiply this number by 5 and round to the nearest integer. This value is X.

 

The minimum of the function (x-2)^2 = Y.

X-Y-2 = C

D) What is the length of the curve of (2/3)x^(3/2) from zero to 4.6? Round to the nearest whole number; this is D.

 E) The limit of ln(x)/x as x approaches infinity is E.

 

F) The fourth derivative of f(x)= 1 + x + x^2 + x^3 is F.

 

G) A hot-air balloon rising straight up from a level field is tracked by a range finer 500 feet from the lift-off point. At the moment the range finder's elevation angle is pi/4, the angle is increasing at a rate of .14 rad/min. How fast is the balloon rising at that moment? This number = Z. Z divided by 28 is G.

 

H) What is the average value of the function f(x)=(x+1)^2 from zero to three? This number is M.

 

Find the volume of the solid generated by revolving the region bounded by the lines and curves y=sqr[9-(x^2)] and y=0 about the x-axis. Multiply the volume by 1/(6pi) to get N.(Note: sqr[]is taking the square root of the value in brackets.)

 

M-N=H

Cache is a regular-sized tupperware container.

Some problems and ideas came from "Calculus - Graphical, Numerical, Algebraic" by Finney, Demana, Waits, and Kennedy. Published by Scott Foresman-Addison Wesley, copyright 1999.
