try integration by parts...that is usefull for evaluating an integral composed of two fuctions, in this case, your first integral include the fuctions \sin {x} and \frac {\11}{x} and your second integral includes e^x and x^2 Remember, integration by parts formula yeilds: {u}{v} -...

f(c) must exist limit of f(x) as x approaches c must exist limit of f(x) as x approaches c must equal f(c) you were confusing continuity with the properties of one-sided limits that states if the right hand limit equals the left hand limit, then the limit as a whole exsists.

a little drawing goes a long way. Just had to use the force of weight, find the distance using hookes law, and throw that into the elastic potential energy formula. Thanks! :smile:

ok, maybe i am missing something here with this problem and it is probably really simple, but here it is: A force of 775N stretches a certain spring a distance of 0.200m. What is the potential energy of the spring when a mass of 65.0kg hangs vertically from it? I have tried conservation of...
