sleepyjess · Answer

I missed the lesson on Friday due to a diving competition and I'm not even sure what the rule is

steve816 · Answer

Hey there, all you have to do is differentiate the numerator and the denominator.

sleepyjess · Answer

That's all there is to it?
So $\dfrac{20x^3-8x}{27x^2+1}$? What do I do from there? Just plug in numbers to find the limit?

steve816 · Answer

Yup! And if you plug in 1, you will get a value! What would that be?

sleepyjess · Answer

3/7

sleepyjess · Answer

Could I ask another quick question? 

How do you differentiate $e^{2x}$?

steve816 · Answer

Great work :D 3/7 is correct. |dw:1478480965554:dw|

hahahahahaha..................

steve816 · Answer

To differentiate e^2x, you must use the chain rule.

sleepyjess · Answer

2e^2x?

steve816 · Answer

Yup, that is the derivative of e^2x !!
