1/15 to 1/17. Textbook chapter 8-4, starting on page 456.
On 1/15, we started by introducing the three basic trigonometric functions: sine, cosine and tangent. We set up the ratios, or fractions, that they used. In particular, look at example 1 on page 457.
Classwork: page 460 #1,2
On 1/16, we practiced using the trigonometric ratios to solve a problem. In particular, look at examples 3 and 4 starting on page 458 in your textbook.
Classwork: page 4461 #44-49
On 1/17, we practiced solving word problems using trigonometric functions.
Classwork: handout provided.
Here's a couple of websites that explains the basic trigonometry we are learning:
