## Limits of Rational Functions – Fractions and Square Roots

This calculus video tutorial explains how to evaluate the limit of rational functions and fractions with square roots and radicals. It provides a basic review of what you need to do to find the limit. Whenever you a complex fraction, you should multiply it by the common denominator. If you have radicals and square roots, you should multiply by the conjugate. This video contains plenty of examples and practice problems for you to work on.

mas naiintindihan ko pa to kay sa sa tc at module namin

Really your teaching is awesome

live thank you

So good

You have no idea how you simplified math and make it fun to learn. Thank you

can you please do a video on proving limits using the epsilon-delta definition please🙏

Can u do on upper bound and lower bound plz

am grateful

You are beautiful. That is all I have to say right now. Wow. So helpful this is so mind-boggling

lim_(x->16)(x^(2)-256)/( 4-sqrt(x)) help 🙂

Bro thanks man……. It is really helpful to me

Question on problem at 5:02 why was the GCF -1?

Wow

what if x is only at numerator

G 180

note:

7:33 in such case you have to multiply the function with the common denominator of the numerator .memorize it

Once again, Thank you! You've really helped me learn a LOT more than any other teacher in my life. I can't thank you enough. You're a blessing to people who have a hard time in Math. God bless you more!! :3

Man In so dumb. I completely forgot that a / b = ac / bc so I was confused on why he didn’t do it to both sides.

What if I had x^2 as a denominator?

this was helpful u saved me from failing tysm

What would you do if you had a problem similar to these, but the limit is exclusively approaching from just the left or just the right?

You are the best online professor in the world.

Very sexy voice. 😀

You are the best😇

You should do asmr bro ur voice is so soothing

You need to tutor mechanical science please😭

is the answer right @ 8:40?? Not 1

Now I gotta go online and teach myself this bullshit cause of this coronavirus shit

Talented I just love really love the way you made me understand many thanks 🤗🤗🤗

root(2)*root(2)= 2 , i think this is right

My tuition should've gone to this guy instead

very clear explanation. thank you sir

It doesn’t make sense that x-4 substitutes to 1 if the limit of x is 4. Shouldn’t it be 0?

Edit: I’m dumb the values cancel

hes so friggin helpful, i passed maths becos of his explaination holy shit THUMBS UP

thanks

Thanks for the tutoring

Wth i got lost in 7:06 where does that -1 came from?
