Calculus without Tears, Vol. 2: Newton's Apple
A TOTALLY different way to learn calculus - you can do it even before high school. You can learn calculus concepts starting from the formula distance = velocity * time. --HomeschoolMath.netYou can learn calculus concepts starting from the formula distance = velocity * time. Yes, that's true. That's what the book Calculus Without Tears is all about. It starts from the simple situation of a runner running with constant speed (velocity), and goes very step-by-step into actual calculus concepts, such as derivative, area under curve (integration), and differential equations --Homeschool Math BlogEven a mathophobe like myself was able to work through the book without trouble, and my third-grade student, who is working on a fourth-grade level in our math program, has made it part-way through the lessons without any trouble. I wanted my husband's opinion on whether this was really calculus, for it seemed way too easy. --EclecticHomeschool.orgYou can learn calculus concepts starting from the formula distance = velocity * time.
