hwk: #1, 3, 4, 6, 11

Trigonometry Problems

Over the past few classes we have solved trigonometry problems using the Trig ratios, sine law and cosine law. A problem set was given today (extra handouts available in class) to prepare for an upcoming quiz.

One more topic to cover before the unit test schedule on Friday Oct 31!

Cosine Law

Cosine law can be used for any triangles to find an angle or side. Remember that the angle and the side that is being solved for need to the the same angle-side pair.

Hwk: #1,2,4,5,7

Sine Law

To find side length or angles of triangles that are not right-angles, we can use sine law. In fact, sine law works with any triangle!

Hwk: #1, 2, 4, 5, 7

Right-Triangle Geometry

Started our next chapter on Trigonometry, focusing on right-triangles.

Hwk: Solve the two triangles

Geometry Test

Today we completed the first chapter on geometry.

Complete the skills questions assigned on Monday's class for Friday.
