# Implicit Surface plot problem

I just tried to plot

25y^2+25z^2 = x^6

This is the equations of the revolution surface of f(x) = (x^3)/5 arround x axis.

(0,0,0) belongs to this surface

( 50^(1/6) , 1 , 1 ), ( 50^(1/6) , -1 , -1 ) and (( -50^(1/6) , 1 , 1 ) belong to this surface

infinite points belong to this surface, but the surface is incorrect shown or it ins't shown at all in geogebra 6.0.604 or 5.0.604. I tried online versions as well.

WolframAlfa can correct display the plot. I've attached two prints: one from wolfram and another from online 5.0.605 pre release geogebra.

Am I doing something wrong? 1

implicitplot no está implementado en GG 3D, solo cuádricas

puedes intentar sqrt(x⁶ / 25 - y²) y -sqrt(x⁶ / 25 - y²) o bien, conociendo que es una superficie de revolucion dibujar la función f(x) = (x^3)/5 y surface(f,2pi,xAxis) 1

Gacias! Habia pensado que podría escribir tales ecuaciones directamente. Lo metodo "surface" ya conocia, pero pensé que el método directo ya funcionaba.
