1. The problem statement, all variables and given/known data Describe using spherical coordinates the solid E in the first octant that lies above the half-cone z=√(x2+y2) but inside x2+y2+z2=1. Your final answer must be written in set-builder notation. 2. Relevant equations ρ = x2+y2+z2 x = ρsinφcosθ y = ρsinφsinθ z = ρcosφ 3. The attempt at a solution Since we are in the first octant, θ will go from [0,π/2]. However the problem comes with describing ρ and φ, Since we are in the first octant I believe that φ will be the same as θ, however for ρ, I substituted in the relevant equations into both equations that were given. ρ= ±1 <-- Unit sphere ρ=√(2ρ2sin2φ)/cosφ <-- Half cone Would I be able to use the positive bound of the unit sphere as the upper limit and the bound gotten from the cone as the lower limit?
