Section 3.3
Question 75

Can you do 75 for me to use as a guide to solve a few more on my own?

75.

-xe^-x+e^-x=0.........factor out common e^-x

(-x+1)e^-x=0....will be equal to zero only if (-x+1)=0=>x=1

I am going to do all the even number questions tomorrow or this weekend. We are almost done with Chapter 3. Chapter 4 starts trigonometry. In trigonometry, we are going to go deep into the subject. This means less questions per week leading to a deeper discussion in terms of why and how.
