Chapter 3: View to the test...

Today we took up some homework (specifically #50 and #51), and I tried to highlight the procedure to solving these complex vector problems.

1. Start with the appropriate vector formula (helps when you try to draw the picture...head to tail, or tail to tail)
2. List the givens.
3. Plot the vectors on the Cartesian Plane.
4. Complete the triangle.
5. Use law of cosines for the magnitude of the vector (usually)
6. Use the law of sines for the direction (usually)
7. State your answer.

Be sure to review some the projectile motion examples tonight and have a good breakfast tomorrow...see you at the test!
