IntegrationSometimes 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. A logarithm is just a misspelled algorithm. #2 20051213 19:12:10
Re: Integrationi 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* #3 20051213 23:22:19
Re: IntegrationNo, 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. Why did the vector cross the road? It wanted to be normal. #4 20051214 10:06:14
Re: IntegrationI 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. A logarithm is just a misspelled algorithm. #5 20051214 13:56:58
Re: IntegrationI 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. #6 20051214 16:21:05
Re: IntegrationIt's not quite impossible. Well, that also depends on your definition of impossible. Last edited by Ricky (20051214 16:22:56) "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."
