1) Twelve students are in a class. They are split so that five go to room A, four go to room B and three go to room C. How many different ways can this happen...
Stuck on these...
:confused:
1.Convert the following equation to Cartesian coordinates r sin (angle) = -2.
2.Convert the rectangular equation y = -5x + 4 to a polar equation.
3.An aircraft going from Atlanta, GA to New York, NY on a bearing of S69oE is traveling at a speed of 430 miles...
What is the difference in the "uniqueness" of the representations of Cartesian coordinates and in polar coordinates? :confused: Also, what is the non-uniqueness?
