Calculus - The laws of limits

[bruhdude]

For those who are confused... direct substitution only works when it does not make the denominator 0; in this case, yes, he could have plugged in 4 for x, but he’s showing us how to solve the problem using limit laws.

This is crazy i just understood a concept in ten minutes which i couldn't in the 2 hours

I love how a random 10 minute over the internet explained the holes that I couldn't understand (i.e. the constant and identity functions) a thousand times better than my textbook.

I don't get it, they'll spend three paragraph pontificating about the obvious then just blank over something like the constant and identity law. Because "As you can see, this is intuitive"

Not even exaggerating. Thank you for the example that tied ALL of it together. Like seriously, thank you.

The part about the identity function, and the constant functions was exactly what I needed. Thank you!

I spent the last few weeks struggling in calculus because of these damn limit laws that my professor assigned numbers to, He is like "alright class, were using LL2, LL3, LL6 in this equation". Its soooo confusing, thank you so much for taking the time to explain this with ease, YOU ARE THE GOAT!

You are an amazing person! Thank you so much for these videos, they are just in time for my studies this year. You can't imagine how much you've helped me since I've discovered you!

[sarthakkanyal]

This was brilliant. I am only 14 and am trying to learn this. This explanation has made everything crystal clear ☺

[kash]

Thank you so much for making these videos. They really help me. Your version of completing the square has helped me greatly in my calculus class. I really appreciate your videos.

you can be my math tutor, but it's going to be a secret.

best teacher in the world ...I pay my honor to him

[cheshireray]

I am still so lost I have no idea what to do or what this is, my teacher has assigned me 18 assignments including our 1st exam on the 1st week of the class.

[shammaalsuwaidi]

why didn't i just plug in the number 4 from the start and skipped all the steps you did ?

[bakowsophia]

Thanks for all your calculus videos
I understand it more than before

[Dirtmagnet]

I just wanted to thank you for these calculus videos. They are very easy to understand and well put together. Big thumbs up from me and subscribed!

[juice]

Thank's a lot. Very easy to understand. Better than my class room.

[venzeti]

Thank you so much for the massive amount of help!!

[littledivergirl]

Why do n in exponent or  ^1/n have to be positive?

[am]

Questions:
If the answer is 0 we counted as doesn't exist? Or..

Can you plug in 0 on the equation for the Questions that have a given values for limits, or we also counted as doesn't exist?

[susanzhu]

Thank you so much! You're an excellent teacher!

I wish you me teaching me at school, you are a very nice teacher.
