need help with the solution

Problem 3. (1 point) Express the point given in Cartesian coordinates in spherical co- ordinates (p. 0, 0). Note: you really only have to do the work for one, if you use a little geometry and your knowledge of the trig functions. A) (2V2, EV2, 0) =_ B) ( - ?V2, Z V2,0) =_ ( 3 V2, - V2, -0) =_ ( -2V2, - 2V2, -0) =_ uswer(s) submitted
