With the rise of online education, you now have the option to earn your degree from the comfort of your own home. However, before making a decision, it’s important to weigh the pros and cons...Euler's formula provides a means of conversion between cartesian coordinates and polar coordinates. The polar form simplifies the mathematics when used in multiplication or powers of complex numbers. Any complex number z = x + iy, and its complex conjugate, z = x − iy, can be written as. φ = arg z = atan2 (y, x).

Usually a path in general is same as a walk which is just a sequence of vertices such that adjacent vertices are connected by edges. Think of it as just traveling around a graph along the edges with no restrictions. Some books, however, refer to a path as a "simple" path. In that case when we say a path we mean that no vertices are …a (directed) path from v to w. For directed graphs, we are also interested in the existence of Eulerian circuits/trails. For Eulerian circuits, the following result is parallel to that we have proved for undi-rected graphs. Theorem 8. A directed graph has an Eulerian circuit if and only if it is a balanced strongly connected graph. Proof.

1.2 Flow visualization - Flow lines † Streamline: A line everywhere tangent to the °uid velocity ~v at a given instant (°ow snapshot). It is a strictly Eulerian concept. † Streakline: Instantaneous locus of all °uid particles that have passed a given point (snapshot of certain °uid particles). † Pathline: The trajectory of a given particle P in time.2.
