I was a liberal arts major in high school, but somehow I ended up cross-applying to an engineering major... Calculus was always hard for me, so this was really helpful. I used to like math, but as I got older, I started to dislike it (I think it was because of work). Now that I understand it while listening, I feel relieved!! This lecture was just right for me. I didn't understand all the lectures;; I think I'll have to listen to them again often, but I feel so secure because I'll own them for life! Thank you so much for the lecture!!
