Sal analyzes the limits at infinity of three different rational functions. He finds there are three general cases of how the limits behave. Created by Sal Khan.

A little bit useful? Are you kidding me? This is gold!
I RARELY SAY THIS BUT I COMPLETELY UNDERSTOOD THIS ONE. JESUS MOTHER OF GOD HAIL MARY.
Beautiful. Your explanations make apparently difficult concepts easier to grasp. Thanks Sal :D
Thank you i have a calculus midterm this week, bless your soul ;w;
You're a life savior.
Thank you soooo much you made it so easy!!!! 👍 your a life saver
I just mastered Limits. They are as easy as x approaching infinity - infinity.
Dear Mr SAL
THANX 4 DIS GREAT VIDEO
Excelent!
Many Thanks!
YES, that was a little useful, sir.
thaaaaaanks forever !

NICE :)
Nice :)
What happens if the numerator is higher than the denominator but it is the negative would than make it negative?
Nice
but the last one is a slamp asymptote right??
well as x nears towards negative infinity, it is on the "negative" side of 0, but there really we don't call 0 "negative" or "positive" 0, so the answer is just 0 :D
I'm confused by the last one. Wouldn't the limit not exist since 4/250 times(infinity) does not equal 4/250 times(-infinity)?
Nope. You cannot approach infinity from both sides as infinity is an end point.
hey wait if anyone can pause after the second problem
2:43
and tell me why it isnt infinity while the bottom is going to have an x in it the infinity in this problem is negative so shouldn't 1 be incredible bigger.. or am i just super wrong here?
i cant work out the logic (my own logic)
tanx
you're welcome.
can someone explain why the LIMIT OF 3 AS "X" APPROACHES INFINITY IS 3?
(end of problem #1)
+Rob Elsas The limit is 3 because 3 * (x^7/x^7) 3*(1) then the X is gone thus the infinity.
good thing you answered his comment more than a year later lmaoooooo
@@GhostMonkey1218 You shouldn't do math in a hurry. Math needs patience.
that is y=3 graph. y value remains the same when x approaches infinity.
