Today we got outside before the rain hit and used trig ratios to estimate the height of one of the large post oaks west of our classroom. We took enough measurements to make sure we knew what we were doing with the calculations when we returned to the classroom.

Our focus was real-world application of trig ratios. We make sketches to match stories from the Discovering Geometry Textbook and took pictures of the resulting work where we found missing distances.

HW #1 is a practice worksheet that is NOT word problems. It is applying what we learned the last class about finding missing sides or angles.

Cell phone calculators may be used for trig ratios. To find angles, make sure you are following the example on the sheet to find an INVERSE ratio (in other words, backwards to find an angle). On the phone, put in the ratio with division, then press 2nd, then the correct ratio. This should give you the angle.
