I remember 2 years ago when I entered engineering that all I used was PatrickJMT or Khan Academy because I saw that you only had a few videos on calculus. About 2 years later, through your hardwork, you have become my main choice of learning for my differential and integral calculus because of the expansion of your video content. I suggest that you consult PatrickJMT and maybe form some sort of joint venture to combine your content. I really love how organized your lecture notes and videos are. I also like how your lecture notes are very simple and easy-to-read without all the complex notation my textbook uses. PJMT has a lot of useful content and many videos but his stuff really needs proper organization. Excellent work! Keep it up. PS: Since you know how to explain complex stuff into simple words, can you explain to me why textbooks make simple concepts so difficult to understand for students? After all, textbooks are suppose to teach us and not confuse us.

Wow, thanks for the awesome comment! :) It makes me so happy that you've been able to follow my updates along the way. It's been a lot of work, but a lot of fun as well. I love what Patrick and Khan do, and it makes me happy that I'm able to help in my own way. Even though I haven't collaborated with them, it feels as though we're on the same team fighting for a similar goal. :)

The thing about math videos is that you only need them when you are learning about what they are explaining. Subscribing doesn't really help me because I don't want to have these videos as soon as they come out, I need them only when I search them up. Your videos are amazing though!! Thank you!

When I took college calculus back in the day most of the time it was essentially a matter of going through the motions using things like the product rule or chain rule vice a more detailed pragmatic approach to solving differential equations. Your explanation on why exactly why the product rule works in this type of equation would have been oh so helpful to me years ago! You don't just teach, you explain...and that is something many instructors don't bother to really do. Your videos are not only an excellent resource of information, but they are also "how to" videos on "how to" educate.

I have always been good at math. I am taking this class at community college and my professor makes it WAY more complicated than it needs to be. To the point where I am so lost. But when I watch your videos I know exactly what's going on and understand how to work my way through the problems. I also like how you throw little things in there which end up helping me alot. For example in this video, you mentioned that the e and the ln have to line up to cancel out. Little things like that help me alot as well. Thank You Krista.

you get one of the factors of x in x^2 to cancel. when you divide every term by x, for that particular term, you get x^2/x, which simplifies to just x.

+wawcrates Yes, you can ignore the constant when you're integrating to find the integrating factor. With these linear differential equations, that constant will ALWAYS end up disappearing later on in the problem anyway, so people tend to leave it out. If you're interested, there are proofs of this online that'll show you why the constant always disappears.
