Any constant multiplied by a variable remains the same when taking a derivative. The derivative of e^x is e^x. E^x is an exponential function. The base for this function is e, Euler...

The Euler Circuit is a special type of Euler path. When the starting vertex of the Euler path is also connected with the ending vertex of that path, then it is called the Euler Circuit. To detect the path and circuit, we have to follow these conditions −. The graph must be connected. When exactly two vertices have odd degree, it is a Euler Path.
