Hey Patrick, I'm a junior in high school and I find your videos rather helpful, especially when the teacher goes so quickly in her lessons at times! I love your calm voice, that's probably why it makes things seem easier than they are ;D ! Thanks !

By: ineedsomesleep. on 29 Nov 08, 13:30:56
Hi Patrick. I'd just like to sincerely thank you for the wonderful range of maths videos. I'm studying engineering at uni over in Australia... Was finding a few concepts hard to grasp in lectures, but they way you explain things makes everything seem a lot more clear. I managed to get 100% in a final exam of a subject with a 35% failure rate, largely due to your explanations ironing out the kinks I had in my understanding. So basically, thank you for explaining things better than my lecturer.

By: ohmannhey. on 24 Dec 08, 23:27:54
You say that "You can think of it as being an area when the function is above the x-axis." That does apply to areas below the x-axis only that they will be negative and therefore subtracted from the positive area. If seeking for the total area you would have to find the "Schnittpunkte" (German for the zeropoints? ... sorry don´t know the English term) in order to isolate the different segments. No? Great show ... wish schools worldwide would have you teaching skills ... Helping me a lot!

By: sincostanraza. on 25 Nov 08, 05:50:10
Here's the story: I need to make a an A grade in Calculus (make or break point) to be considered for admission in the nation's #1 best school for accounting. And I can't afford private tutoring, website with written things don't really help either, and professors don't have time after class. So just to let you know that if I am successful someday making tripe digits(hopefully), you will be a big contributing factor to that. When I am able to establish myself in 3 years, I'll surely meet you.

Hi Patrick, I congratulate you about the vids you're showing. They are very helpful. I have a question though for another lottery scheme. The lottery has a total of 34 numbers of which 7 must be right to win the lottery. But you can pick 12 numbers (out of 34) from which only 7 must be the winning numbers. How do you find this probability?

By: dkw12002. on 07 Dec 08, 04:06:42
Time is a big factor with these tests, so you need to be familiar with those concepts like factoring polynomials, coordinate plane, absolute value, substitution, proportions, combinations, probability, % solutions, slopes, y-intercept, equations for lines, circles, simple geometry, number theory. I would just review any of those SAT prep books. If a person understands those explanations at the beginning of each math section and how to do the first sample problem presented, you will do very well.

By: The4thbassguy. on 01 Dec 08, 20:23:49
i think in order for you to use the comparison test directly to show your series is div, the thing being compared must also be div (like example two) BUT it must also be a lower limit (not an upper limit like in patrickJMT's 2nd ex).

when do you know to ...
By: The4thbassguy. on 01 Dec 08, 20:20:13
when do you know to use limit comparison or direct comparison? do you just use limit comparison when you cant do direct? would you be able to do limit comparison instead of direct and get the same answer? lets say if i did limit comparison for your first example. THANKS ALOT!

I've just got to write in and say how wonderful these videos are. My calculus exam is in a just few hours and these lessons have been SO helpful over the past week of studying. After having a teacher who taught us more about *number theory* than calculus, I needed some serious help. Thanks so, so much for these! :D

the x' is ...
By: andreacone. on 10 Dec 08, 19:07:04
the x' is unnecessary because y'=dy/dx, that means it's taking the derivative of y with respect to x,and x'=dx/dx=1, its the same whether you write it out or not.

Can someone please ...
By: zohx95. on 26 Nov 08, 14:39:56
Can someone please explain to me why the derivative of ln y = 1/y + y' and why that of 1/2 lnx = 1/2 x 1/x? Why shouldn't it be 1/2 x 1/x . x'?
