An ellipse is a closed curve similar to a circle, only it is squashed in on the sides. A circle has a very simple formula for the circumference, but unfortunately, no such simple formula exists...
If you have a rectangular piece of cardboard or cardstock, you can use calculus to construct an open top box with maximum volume. The box is formed by cutting 4 identical squares from the...
For any 3 points in the xy-plane, so long as the points do not lie on the same line, it is possible to find a unique equation for a circle that passes through those 3 points. Recall that the...
Many people young and old know that education is the key to success, especially in this day and age. Our economy is not getting any better. So, with this in mind math is a key ingredient to...
In advanced math and science, there often arises the need to solve systems of equations that are non linear. When finding the intersection points of two conic sections (circles, ellipses,...
Rational functions have the form p(x)/q(x) where p(x) and q(x) are polynomial functions. In algebra and precalculus classes, some math problems ask you to solve for x when you have rational...
Learn the right way to read, understand and solve math story problems.
Teaching math can be as easy as finding the right tools to use, which can get expensive! Here are some tips to making teaching math not only easy, but cheap, using everyday items from home.
A circle is one of the most difficult geometric shapes to compute the area, circumference, etc... It can be difficult for those just learning geometry to understand how to compute the area of a...
Math is not for everyone. Unfortunately, it is a necessary skill in life and a requirement in school for all children, interested or not. So, how do you reach those children that just aren't that...
Sigma notation is very useful when you need to add a large number of numbers together. Although many people find the notation confusing, it's actually very simple to understand when you know how...
Do you ever feel as if the life of a parent is spent waiting? You wait at the doctor's office, in line at the grocery store, in the car at the stoplight. If you have done any amount of time...
Conquering math has very little to do with numbers and a lot to do with confidence. Here's how to get to the point where you don't burst into tears of frustration at the mere mention of...
