Agenda: Feb. 4 HW Check Practice 7.1 Integration overview Quote of the Day: "After years of finding mathematics easy, I finally reached integral calculus and came up against a barrier. I realized that this was as far as I could go, and to this day I have never successfully gone beyond it in any but the most superficial way." -- Isaac Asimov Agenda: Feb. 4 HW Check Practice 7.1 Integration overview
