Hi
0. First of all take a look at this surprising image of Homer doing trigonometry:
Now try to find the height of the tree. Send it to me with the answers to the next part:
1. Find out what is a radian and its equivalence in degrees. Find also which of these units is older. Send me your findings, along with these simple exercises solved:
Express the following angles in degrees:
- 3 rad
- 2π/5 rad.
- 3π/10 rad.
Express the following angles in radians:
- 316°
- 10°
- 127º
You can use these applets to find an approximate answer:
2. Now we are going to try to find out the properties of the trigonometric ratios of angles bigger than 90º, using this applet:
More specifically, try to figure out the signs of sine, cosine and tangent in the four quadrants. Write all in your notebook.
3. And now the last question: What has trigonometry to do with video games? Send me your discoveries.
4. Remember the trees we measured? Take a look at this:
