It's not quite impossible. Well, that also depends on your definition of impossible.
I too taught myself algebra, trig, and calculus, and I commend you for doing so. I dropped out of school in eighth grade, but went to college for engineering some 15 years later. The university wouldn't even let me matriculate until I had earned 20 credits because they thought that I had no shot. Actually I tested out of 3 of my calculus classes without ever stepping foot in a classroom. I asked the head of the math department if I could simply go over the texts on my own and be tested by him directly when I felt comfortable with the material. Thankfully he agreed to allow me to do so.
I see. Thanks!
I teach myself with a book. Saxon Calculus. All Saxon math books are great. Taught myself Algebra 1, 2 and Trig with them, and now calculus. Its a pretty long book, longer then the other ones, and calculus seems to take longer then I anticipated. Before I did 3 lessons a day and would tear through a book in about two months. (interuptions included) but calculus I usually only end up finishing one or two lessons a day. But sometimes you start to speed up as you get more familiar with the concepts, and learning and doing the problems gets easier.
No, that one can't be integrated. At least, no one has discovered how to. But it also hasn't been proven to be impossible, so feel free to have a go and make yourself famous forever.
i tried working out ∫e^(-x^2)dx but i wasn't able to go n e where w/ it. i guess we need a super computer for this one. *shrugs*
Sometimes my book tells me to integrate on a graphing calculator, but I like to do it manually as well for practice. But once in a while I find something I can't seem to integrate.
