I’ve introduced a few derivative formulas but a really important one that Ieft out was exponentials. So here, I want to talk about the derivatives of functions like Two to the x, seven to the x, and also to show why e to the x is arguably the most important of the exponentials. First of…

## Derivative formulas through geometry | Essence of calculus, chapter 3

Now that we’ve seen what a derivative means, and what it has to do with rates of change. Our next step is to learn how to actually compute these guys, as in if I give you some kind of function with an explicit formula you’d want to be able to find what the formula for…

## How to visualize conic sections with a paper model.

Here is a way to explore conic sections:… … how a plane cuts a cone into different curves. Glue the template onto card stock. Cut out the circle and ellipse with a craft knife. Glue the semicircular template into a cone Place the plane straight across the cone, and see that it intersects it at…
