ActorGuy Says:

Jul 27, 2010 - Patrick....love your work. If I could make one suggestion it would be to maybe group these Sequences and Series videos in the typical order given in say either Stewart or Thomas. I'm in Calc II and I'm just sort of figuring out which to do first. But my prof has been mixing everything up for two terms now anyway. LOL.Which text do you base your examples on? We are using Thomas 11th Edition.

Jul 1, 2010 - you're amazing :)

Jun 4, 2010 - @phoLegit this formula works only for geometric series where -1 < r < 1

phoLegit Says:

May 31, 2010 - isnt there a formula for infinite series?where it is a / (1-r) where a is the first number and r is the common ratio

May 30, 2010 - hican you do a video for complicated problems

christopherchubb Says:

Aug 4, 2009 - an absolute is greater than 0 by definition, its superfluous and unnecassary

Jul 29, 2009 - Dude these videos are the best calc videos I've found!! (And I've gone through quite a few. heh.)

scrambledxeggs Says:

Jun 24, 2009 - thanks! this was very helpful!just wondering dont the markers smell a lot?

granadaza Says:

Jun 7, 2009 - Way to go Patrick! Thanks

KingScar06 Says:

May 17, 2009 - Oh nvm, it should be (-1, 1), sorry.

polzowatel Says:

Apr 30, 2009 - ops my bet, same thing))

polzowatel Says:

Apr 30, 2009 - isn't it 0<|x|<1 ?

patrickJMT Says:

Apr 29, 2009 - only if both are positive : )otherwise -3/1 would not work (negative 3 is less than one)

filmcruiser88 Says:

Apr 29, 2009 - is it fair to say the series is convergent if r is a proper fraction (numerator is less than denominator)
