convert the polar equation to rectangular form. 1.) r sec(theta) = 3 2.) r = 4 cos(theta) - 4 sin(theta) convert from rectangular equation to polar form. 1.) x^2 + (y-1)^2 = 1 2.) (x-1)^2 + (y+4)^2 = 17

It would collapse, because you have to exert a downward force to go up. By pushing down on the cardboard that barely holds you, it will probably collapse.

Economic Stability
An economy with fairly constant output growth and low and stable inflation. Basically, there is not too much money being lost, and the money coming in is at a good level. Good enough that there are not too many problems. Does that make sense?

trig
type into google "coolmath graphing calculator" then on the calculator, just type in -4 cos(x/2 + 3.14) + 1 and then press enter on your keyboard. the graph should show up.
