WebA solid in the first octant has the shape determined by the graph of the cone z=\sqrt{x^2+y^2} and the planes z = 1, x = 0, and y = 0. Find the center of mass if the density is given by ρ(r, θ, z) = r. Web22 jun. 2024 · (cosθ + sinθ) = √2cosθ . By squaring both sides, (cosθ + sinθ) 2 = 2cos 2 θ . ⇒ cos 2 θ + sin 2 θ + 2sinθcosθ = 2 cos 2 θ (∵ (a + b) 2 = a 2 + b 2 + 2ab) ⇒ sin 2 θ = …
