Calculus Ladder Problem
posted by Jennifer on .
A ladder 20 ft long rests against a vertical wall. Let \theta be the angle between the top of the ladder and the wall and let x be the distance from the bottom of the ladder to the wall. If the bottom of the ladder slides away from the wall, how fast does x change with respect to \theta when \theta = \pi / 3


5\9 divd 1\3

a 13 foot ladder is leaning against a vertical wall. when jack begins pulling the foot of the ladder away from the wall at a rate of 0.4 ft/s. how fast is the top of the ladder sliding down the wall when the foot of the ladder is 5 ft from the wall?
