After reading my Calculus II book, I am having problems actually applying what Ive learned to a problem. It's very difficult for me to learn off just reading books, (and then applying what ive learned). So here's the problem, find the area under the curve using right end rectangles for: f(x) = x; [0,1]. With 10 rectangles, A(sub10) = ? Thank you. I just understand it but I cannot apply it to what ive learned, that is what is hard. I don't have a math teacher; I'm doing this on my own accord.
