cylinder
consists of all lines paralell and passing through a given curve
for the equation one of the variables will not be squared. the plane is defined by the others
ellipsoid
x^2+y^2+z^2=1
can be over different radius’
equation of a cone
x^2+y^2=z^2
the one on the other side is the axis it is on
cylinder
x^2 + y^2 = r^2
hyperboloid
x^2+y^2-z^2=1
hyperboloid of 2 sheets
-x^2-y^2+z^2=1
eliptic paraboloid
x^2 + y^2 = z
x^2 + y^2 = z
eliptic paraboloid
center axis is z
-x^2-y^2+z^2=1
hyperboloid of 2 sheets
x^2+y^2-z^2=1
hyperboloid
x^2 + y^2 = r^2
cylinder
x^2+y^2=z^2
the one on the other side is the axis it is on
equation of a cone
x^2 - y^2 = z
hyperbolic paraboloid
hyperbolic paraboloid
x^2 - y^2 = z
domain with 2 variable
find both variables such that they satisfy the equation
