Quotient Rule Chapter 32 in review book page 495 and in lesson 13 practice cooldown #4 I have always learned that its the difference (fg'gf'/g^2) not the sum (fg'+ gf'/g^2) divided by the square of the thing being divided. and I looked online for this equation and its different than the one in the book.
On page 192 of the lesson book. problem #4 in lesson 16 on slide 34 it says x=6 when 18x=3 but it should be x=1/6 I think. I was wondering if this was just a mistake.

Re: Math
Hi amahmood16, you are correct on both accounts. The quotient rule does indeed incorporate the difference, not the sum, of f'g and fg', and 18x = 3 does simplify to x = 1/6.

Re: Math
I received my books in May and I am finding a lot of errors and typos in the math sections right now. The Lesson Book had discrepancies compared to the video as well. I just completed Lesson 13 and I had to correct some of the problems in the Lesson Book to match.amahmood16 wrote:Quotient Rule Chapter 32 in review book page 495 and in lesson 13 practice cooldown #4 I have always learned that its the difference (fg'gf'/g^2) not the sum (fg'+ gf'/g^2) divided by the square of the thing being divided. and I looked online for this equation and its different than the one in the book.
