To what length do you have to know Algebra in order to begin teaching yourself the basics of Calculus? How much trigonometry is required? I am in Math 11 on the Canadian system which I am finding very easy. I am going to a summer program in Cornell university and taking Calculus is an option but is is university level and they have a warning that it is a very demanding course. Because of this I wanted to get a head start and try to teach myself some. What background is required? Is it anything like algebra or totally different? Thanks in advanced.
