Equation of circular cone
WebBy simple trigonometry, t a n α = r / z = ( x 2 + y 2) / z. In terms of Cartesian coodinates then, K = { ( x, y, z): x 2 + y 2 = z tan α } and, in terms of cylindrical polars, K = { ( r, θ, z): r = z t a n α, 0 ≤ θ < 2 π }. For the Cartesian, shouldn't it say ( z tan α) 2 instead, since it is the radius? multivariable-calculus Share Cite Follow WebI usually use the following parametric equation to find the surface area of a regular cone z = x 2 + y 2 : x = r cos θ y = r sin θ z = r And make 0 ≤ r ≤ 2 π, 0 ≤ θ ≤ 2 π. I've now have a …
