A line of best fit is usually drawn on a scatter diagram. It's drawn so that the points are evenly distributed on either side of the line. There are various methods for drawing this 'precisely' but ...

As the tangent is a straight line, the equation of the tangent will be of the form \(y = mx + c\). We can use perpendicular gradients to find the value of \(m\), then use the coordinates of P to find ...

' Immersive Math ' is a free textbook site that makes linear algebra, a field of mathematics that studies calculations such as vectors and matrices, easier to understand by providing interactive ...

Trend lines are a type of regression analysis, which is a way to study the relationships between variables. In the context of small business, trend lines are often used to show sales trends and can be ...

Results are obtained for integral equations on the half line, and for corresponding finite-section equations. Convergence, in the sense of uniform convergence on every finite interval, is proved under ...

Math equations can feel like a banal abstraction without images to make sense of the strings of numbers, letters, and Greek symbols. Consider the Pythagorean theorem, an essential relation in geometry ...
