Late last month, we have talked about fractions with terminating decimals as well fractions with non-terminating decimals. We ended up with a conjecture that a fraction is a terminating decimal if its denominator has only the following factors: 2 (or its powers), 5 (or its powers) or both. In this post,we refine this conjecture. This conjecture […]

## Curve Sketching 3: Understanding Vertical and Horizontal Asymptotes

This is the third part of the Mathematics and Multimedia Curve Sketching Series. In the first part of this series, we have learned how to sketch linear functions, while in the second part, we have learned how to sketch quadratic functions. In this post and the next post, we will discuss about another important property […]

## Vectors, Parallelograms, and Commutativity

Basics of Vectors Scalar quantities are quantities specified by magnitude. Mass, area, density are examples of scalar quantities. There are quantities that have both magnitude and direction. For example, when we say 2 kilometers east, 2 kilometers is our magnitude and east is our direction. Quantities with both magnitude and direction are called vectors. In […]
