## Centroid of a Triangle – Definition, Formula and Examples

The centroid of a triangle is a point that represents the intersection of the three medians of the triangle. On the other hand, the medians are the segments that connect the vertices with the midpoints of the opposite side. In this article, we will learn about the...

## Incenter of a Triangle – Definition, Formula and Examples

The incenter of a triangle is a point that represents the intersection of the three bisectors of a triangle. Furthermore, the incenter can also be considered as the center of a circle inscribed in the triangle. We can find the coordinates of the incenter using a...

## Circumcenter of a Triangle – Definition, Formula and Examples

The circumcenter of a triangle is the point where the three perpendicular bisectors of the triangle intersect. The circumcenter can also be defined as the center of the circumscribed circle that passes through the three vertices of the triangle. The location of the...

## Product Rule – Formula, Proof and Examples

The Product Rule is one of the main principles applied in Differential Calculus (or Calculus I). It is commonly used in deriving a function that involves the multiplication operation. The product rule was proven and developed using the backbone of Calculus,...

## Product Rule – Challenging Examples and Practice Problems

Derivation exercises that involve the product of functions can be solved using the product rule formula. This formula allows us to derive a product of function such as but not limited to fg(x) = f(x)g(x). Here, we will look at a summary of the product rule....
