A plane is defined by the point (3, 4, 5) and normal vector (1, 2, 3). Determine the normal form of this plane.
💡 Hint: Substitute the point into the normal form structure.
Given the angles α = 45°, β = 30°, γ = 60° and a distance p = 10, express the plane in normal form.
💡 Hint: Convert angles to cosines before substitution into the normal form equation.
