Scribe Post April 22

Hi guys, today we studied about solving problems using Trigonometric Method: Pythagorean Theorem, Law of Sine and Law of Cosine.

You can use Law of Cosine when you have Side Side Side (SSS) or Side Angle Side(SAS). Otherwise, you can use Law of Sine to solve the problems.

We also did an example by using Law of Cosine and Properties of angles. Here are the answers:
_ Magnitude of the resultant vector: 0.0644 N
_ The direction of the resultant vector: bearing 70.48 degree.

The next scribe will be ickie .
