# Interactive Math Applets for *Everyday Calculus*

Not only are you surrounded by math, thanks to technology it’s something you can interact with directly. That’s why I’ve created the interactive math applets linked to below. These are connected to math content discussed in *Everyday Calculus. *Check out the Interactive Math page for more applets.

#### Trigonometry

How trigonometry can help you get better sleep (see Figure 1.1 in *Everyday Calculus*)

#### Derivatives and Their Applications

Secant and tangent lines; average and instantaneous rates of change (see Figure 2.2 in *Everyday Calculus*)

The mathematics of coffee cooling (see Figures 2.3 and 2.4 in *Everyday Calculus*)
