A plane is any flat surface with two dimensions that are extended infinitely. It has zero thickness, zero curvature, and its width and length are infinite in extent. This means it has no borders or edges and so you can’t see the whole of the plane at any point. To help you visualize a geometrical …
Many problems in math or science use quantities or numbers that are relatively easy to use or mentally picture such as 5, 10, 10,000, 6.5, etc. However, real-life situations in science or engineering often call for dealing with numbers that are either too large or too small such as the following: Handling and representing such …
A hyperbola is formed when a plane slices through the edges of a right circular double cone at an angle greater than the slope of the cone. It has two symmetrical components which look like two opposing bow-shaped curves. A hyperbola can also be described as the set of all points (x, y) in a …
Direct variation is a mathematical concept that describes the relationship between two variables. The relationship can be expressed in the form of an equation whereby one variable is equal to a constant times another variable i.e. y =kx where y and x are variables and k is a constant. The value of y, therefore, changes …
We are always interacting with ratios often without realizing it. From comparing the heights of different people to comparing crowd sizes, ratios are an everyday experience. Ratios are a useful way of comparing two or more quantities of different things in order to better understand how they relate to each other. They can be expressed …
When two specific lines intersect at 90°, they are known as perpendicular lines. In other words, two lines are perpendicular to each other when a right angle is formed at their point of connection. A right-angle symbol shows the perpendicular lines in this right-angled triangle In geometric shapes, the right angle symbol denotes perpendicular …
