@doriswuchun It's pretty much 2+2 = 2(2) since there are two 2's in (2+2). So if you do √2 + √2 there are two √2's and it becomes 2√2. The -1 is still the numerator in all this so the end result is: -1/ 2√2. No?
great explanation. Only problem is that you get bogged down with things that should be already known in 6th grade like 0 denominator, expanding brackets and binomial theorem with square. If you missed these stuff out - that should be self explanatory for a calculus student - you could do it faster, and much more efficiently. Its a bit slow. Maybe just for me, but i already got most of it at the first example, and by the second it was entirely clear. I dont know bout the others.
Yeah, he does a good job. But in my opinion if people don't know simple factorising, canceling, and how to expand (a+b)^2 they shouldnt be learning calculus, they should be learning algebra one and two, and once secure on that, only then learn calculus. You know, its like if i cant ride a bicycle, but i want to learn to do backflips with a stunt motorbike. Math builds on itself.
Fantastic videos. Clear, succinct, and accessible instruction. How is it that I'm learning more from videos on Youtube than I am from a college course I'm paying thousands of dollars for?
BTW, I love how often you're like, "that's totally wrong". It should be your catchphrase. It's true to your style.. no beatin' around the bucket in calculus. It's not partially wrong, not just a little wrong, it's wrong. Love it! :P
Wow, the way u teach is just incredible. You don't assume anything. Although the topic is limits, you break down the algebra to make sure nothing is missed. I cannot see anyone not learning from these videos. Very well done.
u xplains better than ma university lecturer. Tnx a lot am gona do wel!

i think talking about people's common mistake is a great thing becuz it make some people who are not good in math to understand better like me XD

how did 1/√2 + √2 become 1/2√2 ? please explain because i'm really confused..
i'm somewhat slow when it comes to this stuff... thanks in advance!
