Transforms points between Polar/Spherical/Cylindrical/Cartesian coordinate systems
CoordinateTransform[t, pt]
CoordinateTransform[t, {pt1, pt2, …}]
CoordinateTransform[ "Polar" -> "Cartesian", {r, θ}]
→ {r*Cos[θ], r*Sin[θ]}CoordinateTransform["Spherical" -> "Cartesian", {1, π / 4, π / 2}]
→ {0, 1/Sqrt[2], 1/Sqrt[2]}CoordinateTransform["Cartesian" -> "Polar", {x, y}]
→ {Sqrt[x^2 + y^2], ArcTan[x, y]}
