Darn it, it DID show up twice — when I used “view all comments.” AND, I no longer see any way to remove one of my own comments! My apologies.

I apologize if this shows up twice — I posted before, it said OK but I don’t see it. My comment may have been made and answered before. If x is the distance from the runner to first (not home), so dx/dt is (-20), doesn’t that simplify the differentiation (of x^2 instead of (90-x)^2) but get the same answer?
This has probably …
This has probably already been asked and answered somewhere, but if you define x as the distance from first base (not home plate) to the runner, and dx/dt as (-20), does the math work the same but the differentiation is simpler? Because you are differentiating x^2 instead of (90-x)^2?

@sweepmastara
actually it’s -20/sqrt(5) but then he rationalized the denominator so it becomes -4sqrt(5)

Durant3535, you can always replay the video as often as you like. PatrickJMT does a great job.
Thanks!!

then about 10 other people will say: you go too slow
good.. just slow …
good.. just slow down a little
What i still don’t …
What i still don’t understand is the difference in when to use x or y in this type of problem.
nice example. thank …
nice example. thank you
i’m pretty good …
i’m pretty good with calc, so i was going to get a 5, but with your help i might come close to a perfect score. lol. thanks so much and keep up the great work!
well this problem …
well this problem was a lot simpler than I thought.
yes
yes
Noob question! Did …
Noob question! Did he simplify the final equation w/o using calculator? If so… how?
Yeah i suck at math… i know…
Thank u
Thank u
I agree. I actually …
I agree. I actually skip class now and watch your videos instead! You should be paid to be the instructor!!!!
i hope you don’t …
i hope you don’t let these annoying complainers who can’t understand a good explanation get on your nerves Patrick. i would hate to see less posted videos because of these ingrates.
i found the explanation very good and thorough, given that you understand basic algbera.
i don’t even count on my professor to teach me anymore, i watch these videos and they’re 10 times more useful than sitting in a lecture
keep up the good work!
Sounds like an …
Sounds like an evenly balanced equation to me, Patrick. He might not agree though; that is, if he didn’t work out the algebra to see it’s balanced.
Maybe you should …
Maybe you should take algebra before you try to learn calculus then…
you annoy me, so i …
you annoy me, so i guess it all evens out.
This video annoyed …
This video annoyed me.
Rather than work out stuff you just left them as algebra.
