Problem #1:

A ladder 10 ft long rests against a vertical wall. Let theta (I don't have anything on my computer that gives the symbol) be the angle between the top of the ladder to 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= pie/3

sorry I do have some of the symbols in my computer but they don't show properly on here.

Problem #2:

Find the limit as x approaches 0 : sin(4X) / sin(6X)

sorry again the symbols just don't show up properly.

Any and all help would be appreciated
