Functions of two variables can be visualized in many ways: heat maps in 2D, contour curves in 2D, wireframes in 3D, surfaces in 3D. We begin by defining a function of two variables, building an array ...

Presenter 2: We are looking to see if there is a link between the volume of air in the beaker and the length of time the candle stays alight. Presenter 1: Use a line graph when both variables use ...

Apple improved the Math Notes feature in iOS 26 and iPadOS 26, allowing users to input equations to create graphs in three ...

In this video we will learn about the plotting of graphs for a pair of linear equations in two variables. Two straight lines are obtained when we plot a pair of linear equations on the graph paper ...

For example, you could look at the daily sales of ice cream and the daily high temperature as the two variables at play in a graph and find a crude linear relationship between the two. A positive ...

A perfectly negative correlation means the relationship that exists between two variables is exactly opposite. In a line graph, you would see a downward slope. In economics, price and quantity are ...
