Homework Statement
Put the equation: p = 2 sin (x) cos (y) into rectangular coordinates. Identify the surface
The Attempt at a Solution
I tried to look at all the identities but I can't seem to figure out which one to use. I have the solutions to this problem, which follows:
p^2 = 2 p sin x cos y
=> x^2 + y^2 + z^2 = 2x (Where did this come from?)
=> x^2 - 2x + y^2 + z^2 = 0
=> (x^2-2x+1) + y^2 + z^2 = 1, which is a sphere of axis (1,0,0)
Can anyone explain the solution? Thank you
