Some exercises with coordinate systems a) find the conversion from spherical (aka "polar") to cartesian coordinates, i. e. the functions z(r, 0, 6), y(r,0,) and 2(r, 0, 0). also find the inverse functions, r(r, y, 2), etc. b) find the conversion from cylindrical to cartesian coordinates, i. e. the functions r(p, o, 2), etc. also find the inverse functions, p(x, y, 2), etc e) a particle starting from the origin moves in the f direction with velocity vo and polar angles o and 0, such that = v, f. expressõ in cartesian coordinates.

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
