This week I killed that test, I’m pumped haha. Anyway we pretty much jus reviewed and did the study guide all week so I will talk about some thing we learned the week before. The good ole product rule. When doin the product rule you just have to remember the formula which is:
( copy 1st ) ( derivative of 2nd ) + ( copy 2nd ) (derivative of 1st )
Here is an example:
( x^2 + 2 ) ( x – 3)
( x^2 + 2 ) ( 1 ) + ( x – 3 ) ( 2x)
X^2 + 2 + 2x^2 – 6x
= 3x^2 – 6x
The quotient rule works the same way, the only difference is the formula. …
( copy bottom ) ( derivative of top ) – ( copy top ) (derivative of bottom) / ( bottom ) ^2
I find the quotient rule is a little harder than the product rule just because the formula puts it in fraction form, but I works the same way.
