1. The problem statement, all variables and given/known data Sketch the solid whose spherical coordinates (ρ, φ, θ): 0≤ρ≤1, 0≤φ≤(pi/2) 2. Relevant equations 3. The attempt at a solution I was thinking that since ρ represented the distance from the point of the origin and φ represented the angle between the positive z-axis and the ray through the origin and any point, that the surface represented by such an inequality would be something like the top hemisphere of a 3d sphere. Any feedback would be appreciated.
