    Describing a region using spherical coordinates

    You get z=√(x2+y2) ≤ ρ ≤1

    Describing a region using spherical coordinates

    You're right, I made a mistake when i factored it out, if i simplify I get 1 = tanφ, which gives me φ= π/4. Which confuses me, would the lower bound for ρ be π/4 or would that just be the upper bound for φ?

    Describing a region using spherical coordinates

    Homework Statement 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. Homework Equations ρ = x2+y2+z2 x = ρsinφcosθ y = ρsinφsinθ z = ρcosφ The Attempt...
