Conquering calculus1998

This gentle guide for the mathematically challenged paves the road of algebra, geometry, and trigonometry that leads to calculus, without restorting to complicated symbols or formulas. Sticking with simplicty, Weaver opens the door to the previously daunting world of calculus, and shows us with everyday examples and clear language that we can romp around with integrals and derivatives, instead of running away from them.
