This paper presents a conceptual analysis for students' images of graphs and their extension to graphs of two-variable functions. We use the conceptual analysis, based on quantitative and ...

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 ...

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 ...

Microsoft Excel can perform numerous statistical functions, as well as create charts from statistical data. Statistical data includes numeric variables or word variables, also called categorical ...

Explore how covariance reveals relationships between variables, its role in financial planning, and its application in the stock market for better investment strategies.

In this video we will learn about the UP Board Class 10th Mathematics topic, plotting of graphs for a pair of linear equations in two variables. Two straight lines are obtained when we plot a pair of ...
