How do you plot cylindrical coordinates in GeoGebra?
.
1) Open up GeoGebra 3D app on your device. .
2) Go to MENU, OPEN.
Under SEARCH, type the resource id (in URL above): tV6CZy9Y .
3) If you want to see the cylinder, find the variable j and set it equal to true (instead of false). .
4) The slider a controls r.To convert a point from cylindrical coordinates to Cartesian coordinates, use equations x=rcosθ,y=rsinθ, and z=z.
To convert a point from Cartesian coordinates to cylindrical coordinates, use equations r2=x2+y2,tanθ=yx, and z=z.
How do you draw a cylindrical coordinate system?
To form the cylindrical coordinates of a point P, simply project it down to a point Q in the xy-plane (see the below figure).
Then, take the polar coordinates (r,θ) of the point Q, i.e., r is the distance from the origin to Q and θ is the angle between the positive x-axis and the line segment from the origin to Q.

Cylindrical and Spherical Coordinates Recall that in the plane it is
Cylindrical coordinates (r, θ, z) of a point P(x, y, z) are obtained by using polar coordinates (r, θ) of the projection in the x-y plane and leaving z unchanged: x = r cosθ, y = r sinθ, z = z To convert from rectangular to cylindrical coordinate we use: r2 = x2 + y2, tanθ = y x , z = z |
