Using Substitution Homogeneous and Bernoulli Equations
... Sometimes differential equations may not appear to be in a solvable form. However, if we make an appropriate subsitution, often the equations can be forced into forms which we can solve, much like the use of u substitution for integration. We must be careful to make the appropriate substitution. Two ...

... In the coordinate plane, a point is described by an ordered pair of numbers called the x and y coordinates of the point. Example: Sketch the coordinate plane and review the four quadrants, the two axes, and the origin. In what quadrants are the x-coordinates positive? negative? In what quadrants are ...

Homogeneous coordinates
In mathematics, homogeneous coordinates or projective coordinates, introduced by August Ferdinand Möbius in his 1827 work Der barycentrische Calcül, are a system of coordinates used in projective geometry, as Cartesian coordinates are used in Euclidean geometry. They have the advantage that the coordinates of points, including points at infinity, can be represented using finite coordinates. Formulas involving homogeneous coordinates are often simpler and more symmetric than their Cartesian counterparts. Homogeneous coordinates have a range of applications, including computer graphics and 3D computer vision, where they allow affine transformations and, in general, projective transformations to be easily represented by a matrix.If the homogeneous coordinates of a point are multiplied by a non-zero scalar then the resulting coordinates represent the same point. Since homogeneous coordinates are also given to points at infinity, the number of coordinates required to allow this extension is one more than the dimension of the projective space being considered. For example, two homogeneous coordinates are required to specify a point on the projective line and three homogeneous coordinates are required to specify a point in the projective plane.
