A parabola is a curved line, of course. How is a parabola curved though? And how do we indicate a parabola, in math, of course?We can define parabolas using the way parabolas are curved.And we can indicate a parabola putting it in an equation, called an equation of a parabola.We can put the same parabolas many different ways. In other words, the parabola themselves are the same, but their equations are different. And in fact, the same is true for any other curves, too.This book is on parabolas, and in math, we put them in equations, so it covers equations for parabolas, that is, equations of degree 2, contains lots of examples in such, and thus, helps get used to algebra and graphs on such equations. This is in fact, a book of examples, so ideas or rules as formulas, identities, etc., or laws or principles are explained through examples. Each example is fully worked out and detailed, together with a summary at each end. So this book helps develop and grow manipulation and calculation technics on equations for parabolas and their curves, that is, parabolas, and thus, will help strengthen problem-solving skill.
