This document discusses several real-world examples that demonstrate different types of trigonometric functions, including a quadratic function to model the bottom of an egg, an absolute value equation for a window frame, a linear function for the angle of horns in a photo, and parabolic functions to model parts of a skateboard and microwave.

1. Real World Trigonometric Applications Matt and Michael

2. The bottom of the egg allows for a quadratic, or parabolic, function f(x)=.38x^2

3. The framing on the window lends itself to an absolute value eqation! f(x)= /1 | x |

4. The angle of the photo and the formation of these Blue Devils feature a linear function through the center of the horns, for the most part.

5. Another real world linear function is the side of this skate board until it curves into a rough parabolic or almost circular function at the head of the skateboard.

6. This piece of the microwave features a parabolic function. Something difficult about applying this picture to geometer’s sketchpad was the fact that the point of inflection went beyond the picture.
