Anyone who can rewrite the set R={(x,y,z)│0≤y,x^2+y^2+z^2≤1} to spherical coordinates and explain how we do the rewriting?
well, what shape is it? can you tell?
it is a "half ball" so to say... with a nondefined area along one of the sides if i had to guess
I don't know about a non-defined area, but it is a half a sphere, yes
and along with that i know that x=p cos(t) sin(h), y=p sin(p) sin(h) and z=p cos(h).
sphere coords use 3 angles dont they?
or rather a radius, and 2 angles
no, just two
polar is (r,t) ; sphere uses that same (r,t) and adds in .... is it an angle from the z axis ?
But would the rewirting just be a substiuation of the x,y,z values i said?
x = cos t y = sin t ; these are the same as polar since they are reflections onto the xy plane
