L'HOP STYLE (Parody of Gangnam Style)

A fun music video over using l'hopitals rule, and some associated tricks. Here are the Lyrics (WRITTEN BY LILL SHELL)

When you have a function and it's indeterminate
Ratio zero over zero when you take the limit
Positive infinity over infinity
As n goes infinite
Just use L'Hop's rule
Take the derivative of the numerator right away
Then take the derivative of the denominator next
Apply the limit to the new ratio that you just made
To get your answer
But don't forget that every time you
Must check it! Hey! Must check it! Hey?
Zero or positive infinity
Just check it Hey! Just check it! Hey!
Make sure it works for L'Hop's Rule (hold out)
Work it L'Hop Style

L'Hop Style
Work, work, work, work, work it L'Hop Style

L'Hop Style
Work, work, work, work, work it L'Hop Style
Eh calc is crazy
Work, work, work, work, work it L'Hop Style
Eh calc is crazy
Work, work, work work
Eh eh eh eh eh eh
Sometimes you might get a different indeterminate
Other than the two allowed for using L'Hop's rule
In that case there are some tricks that you can use to fix it
So that you can use L'Hop's Rule
Here are tricks for you
If you don't have a denominator. Flip a factor
Flip it down from the numerator. Flip it down
When there's a power in your limit use the natural log
Logs make it work

 
But don't forget that every time you
Must check it! Hey! Must check it! Hey?
Zero or positive infinity
Just check it! Hey! Just check it! Hey!
Make sure it works for L'Hop's Rule (hold out)

Work it L'Hop Style
L'Hop Style
Work, work, work, work, work it L'Hop Style

L'Hop Style
Work, work, work, work, work it L'Hop Style

Eh calc is crazy
Work, work, work, work, work it L'Hop Style
Eh calc is crazy
Work, work, work work
Eh, eh, eh, eh, eh, eh
L'Hopital likes repetition
Repeat repeat and do it all again
As long as conditions still are met
Repeat repeat and do it all again
You know what I'm saying
Work it L'Hop style
Eh eh eh eh eh eh

Eh calc is crazy
Work, work, work, work
Eh eh eh eh eh eh
Work it L'Hop Style
