Chapter 3, Problem 63

(choose chapter or problem)

The base of the Great Pyramid at Giza is a square that is 230 m on each side.


(a) As illustrated in the accompanying figure, suppose that an archaeologist standing at the center of a side measures the angle of elevation of the apex to be \(\phi=51^{\circ}\) with an error of \(\pm 0.5^{\circ}\). What can the archaeologist reasonably say about the height of the pyramid?


(b) Use differentials to estimate the allowable error in the elevation angle that will ensure that the error in calculating the height is at most \(\pm 5 m\).
