Give me a firm place to stand and i will give your rounding errors far away Ways to describe the position of a point space. CartesianA point is expressed as P = xi + yi + zi, where i, j and k are unit vectors parallel to the axes of the coordinate system.`To Cylindrical` `r = sqrt(x` ^{2}`+y` ^{2}`)` `θ = arctan y/x` `z = z` `To Spherical` `r = sqrt(x+y+z)` `θ = arctan y/x` `φ = arctan( ` `sqrt(x+y+z) / z ` `)` CylindricalA point is made up of r, θ and z. θ is the angle around the z-axis. r is the distance to the point from the z-axis and z is the height of the point above the x-y plane. `To Cartesian` `x = r cos ` `θ` `y = r sin` ` ` `θ` `z = z` `To Spherical` `r = sqrt(r` ^{2}`+z` ^{2}`)` `θ = ` `θ` `φ = arctan r/z` SphericalA point is made up of r, θ and φ. r is the distance from the origin to the point. θ is the angle around the z-axis and φ is the angle between the z-axis and line to the point from the origin. `To ` `Cartesian` `x = r ` `cos ` `θ` ` ` `sin ` `φ ` `y = r sin ` `θ` ` sin ` `φ` ` ` `z = r cos ` `φ` `To Cylindrical` `θ = ` `θ` `r = r sin ` `φ` `z = r cos ` `φ` |
