Hi! Thank you so much for your videos! I discovered them when we started series and sequences in my Calc II class, and they help to understand the topics so well!
Anyway, I'm working on the Ratio test and I'm not sure how to deal with (5n)!. I know that n! breaks down into n(n+1)(n+2).... but how does (5n)! break down?
Hey, so first off, your videos are awesome. They have been a ton of help.
My questions was this: is there an easy way to factor cubic functions?
I'm working on a problem that asks me to find the intersecting points of a cubic function and a horizontal line. My professor suggested that I use the chain rule to work this out but I'm not how that applies.
hm... well you could try the rational roots theorem to find roots and then do long division to factor; however this would only work if there are rational roots...
Hi dear, I am a first year mathematics student in the University of Glamorgan in the United Kingdom. I would like to thank you alot for the effort that u are making in uploading all the videos. My suggestion is if you could please upload couple of more examples of (absolute values and inequalities, we call it inequalities and mudulus functions) and may the examples include valid and invalid answers plus if you could please explain them by dividing a line in to different segments. i hope i am able to watch it before 8th of december due to my test day that is arriving soon. regards Wakil,

well, not much you can do with [5n] factorial other than break it down as
[5n][5n-1][5n-2]...[3][2][1]
Oh, alright. Thank you! I wasn't sure if it broke down like that or another way. :)
maybe there is something else you can do to it... i am just unaware of what it would be : )

Any help would be great!

Hey Patrick! I was wondering if you can do some examples on how to find Slant asymptotes (involves long divisions?)
Thanks!

Wakil,
Show that Sf(x)dx = xf(x) -Sxf'(x)dx, and use it to evaluate Ssin-l (x)dx.....the capital 'S' represents the integral sign.
I had a hunch that it somewhat looks like the IBP formula, but I could not make it work.
BTW I believe what you are doing is awesome. I actually have another question but I don't want to be a question hog, and it's a long question.
I would love to see you do some fancy word problems with differentials, or integrals.
Never Mind, I figured it out, You do need to use IBP. I just missed a minor detail.
