A point in rectangular coordinates is given. Convert the point to polar coordinates?

Ok, you know the X value which is -2. (this indicates that your travelling in the opposite direction 2 units) now you have to figure out what that 3/2's pi means) well: when dealing with polar coordinates your working in radians from the +x axis and a distance from that. In otherwords, this is the angle starting at the horizontal right axis, and travelling around in a counter clockwise direction.

The nomenclature is (radius, theta) where radius is the distance from the origin (in your case -2) and theta (in your case 3/2 pi) so to solve this we need to go 3/2 pi from right. Since there are 2pi in every circle we will end up on the negative -y axis. We need to move -2 units from there so we end up in Cartesian coordinates = (0,2) please watch this video: http://www.youtube.com/watch?v=r0fv9V9GH...

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
