Calculus for dummies, the book

[QuantumTheory]

Someone on this forum mentioned to me the book calculus for dummies is a book, and even though the author mentions what he says isn't strict by any means, people have told me its a waste of money. Is this true? At least, it makes the concepts easier to grasp.

For an example the integral (the anti derivitave ) he explains that the interval with a limit (without the +C) from a to b is like taking a object and its curvature and the a is the bottom and the b is the top. is this a good way to look of it?

I don't understand quite what you mean by "taking a object and its curvature" here--could you quote a paragraph of the book? An integral can be understood as the area underneath a curve from one point to another, if that's what you mean...see the diagram here (http://members.aol.com/purseweb/integral-def.jpg), where the value of the integral is equal to the purple area under the curve, with a and b being two points along the x-axis.

Are you sure there was not a picture to look at along with the explanation?

my friend has it and he says its SO helpful
