WebMar 24, 2024 · A plane coordinate system whose axes are not perpendicular. The x-coordinate of a point P is the abscissa of its projection onto the x-axis in the direction of the y-axis, and the y-coordinate is similarly determined. Unlike in the more general case of affine coordinates, in oblique coordinates, the unit length is the same on both axes. If the … WebThe simplest 3D case of a skew coordinate system is a Cartesian one where one of the axes (say the x axis) has been bent by some angle , staying orthogonal to one of the remaining two axes. For this example, the x axis of a Cartesian coordinate has been bent toward the z axis by ϕ {\displaystyle \phi } , remaining orthogonal to the y axis.
