Conic Sections
Students need the best teacher, so
you need examples, because examples are the best teacher. All the examples here
are fully worked, and help you do math better.
This book is for your algebra, and
you will grow it through examples. Some examples may look too easy or too
hard. It all depends on your skill of algebra. Whatever your skill may be
though, you can grow yours following the steps in each example. Each is
detailed so that you can learn how to handle math expressions fast, and
increase your caliber in algebra quickly, as well as properly.
And this book covers conic sections,
often just called conics.
What then is conics about?
Conics is about equations indicating
lines, parabolas, circles, ellipses, and hyprbolas, which are common curves
you often need to handle doing school math.
Among all those, most often used are
the equations indicating lines, that is, equations for lines, often called
linear equations and also, equations of degree 1.
The next is, that is, the second
most often used are the equations indicating parabolas, equations for
parabolas, often called quadratic equations and also, equations of degree 2.
And the others in conics are circles,
ellipses, and hyperbolas.
This book explains what such an
equation is about, how it gets made, how it behaves, what we can do with it, and
how to use it. What then is it for?
For instance, a line is a math
concept, and gives us a math tool called a slope. And we use it to see how
fast or slow things can change.
Who doesn’t know though, what a line
is? A line is the simplest of all, isn’t it? So why bother learning it?
When it comes to a problem though,
it is not that simple. It is often the case students get trouble finding the
line they want or using a line so that they can get to the solution. It’s
primarily because they are not quite sure of the concep of a line, math idea
called a line and what a line is about in math.
Thus, this book helps get the idea
of a line, the concept, and you will get to see how to find it and how to use
it properly, because the book explains what a line is and how it works,
together with its nature so that you can develop your own idea to find it and
to make use of it, solving problems, of course.
And the same is true, also, for
parabolas, circles, ellipses, and hyperbolas.

downloaded clicking the logo button below.
Using a pdf reader, your reading the sample is much easier.

May your math run very well.
