This week was LOOOOOGGGGGG week. we learned a buncha stuff about logs this week, well, mostly natural logs, but it wasnt too bad....
how to expand natural logs:
1) ln xy^3/10
ln x + ln y^3 – ln 10
= ln x + 3ln y – ln 10
how to condense logs:
3ln x
= ln x^3
how to take the derivative of a natural log:
-Use this formula: d / dx ln u = 1 / u * d (u)
ex: ln x^2 - 1
1 / x^2 - 1 * (2x)
2x / x^2 - 1
