On the other hand, the graph of the log passes through (1, 0), going off to the right but also sliding down the positive side of the y-axis.Remembering that logs are the inverses of exponentials, this shape for the log graph makes perfect sense: the graph of the log, …
The choice of the values of x in the table correspond to x and y intercepts, maxima and minima points. These are useful points to graph the sine function over one period: [0 , 2p].To graph f, we first graph the points in the table then join these points.
An interactive turorial on the graph of the general tangent function and its properties such as period, phase shift and asymptotes.
Arrange positive and negative charges in space and view the resulting electric field and electrostatic potential. Plot equipotential lines and discover their relationship to the electric field. Create models of dipoles, capacitors, and more!
