Concept #1: Intro to Trig Review

Concept #2: Trig Review & Using Arctan

Concept #3: Using Sine and Cosine

Concept #4: Vector Problems (Practice Intro)

Practice: PRACTICE 1: You move 15 m due east, then 30 m north, then 25 m east. Draw displacement vectors and find the magnitude and direction (use the *absolute* angle) of your total displacement.

Practice: You move 4 m due east, 5 m due north, and 6 m due south. What is the magnitude and direction (use the absolute angle) displacement would you need to *return* to your point of origin?

Practice: You move 5 m along the positive X axis, then 10 m directed at 53 degrees above the negative X axis. Find the magnitude and direction (use the absolute angle) of your displacement.

Practice: You move 2 m due north, then 5 m directed at 53 degrees east of north. What magnitude and direction (use the absolute angle) displacement would you need to *return* to your point of origin?
