Suppose the

angle (theta) between vectors u and v is 30, u = (5,4) and llvll = 6.

a. How many possibilities are there for v?

b. Sketch a diagram that shows u and v as position vectors.

c. Find horiztonal and vertical components for a vector v that satisfies the above criteria.

Consider a

triangle with standard labeling in which alpha = 3pie/5 rad., b = 7 and a = 12

a. Is it uniquely determined? Justify your response.

b. Solve the triangle.

Bill is 10 miles due north of Ron. Sue is 15 miles away from Ron and 7 miles away from Bill, in the north east. What bearing should Ron take to reach Sue?

Thanks for all the help in advanced. (A quick note, please don't just provide me for answers. I'd appreciate details of how you got your answer and

__why__.)
