Line Diagrams Math. They are particularly useful for situations like illustrating changes that happen over a period of time or other variables. The line graph comprises of two axes known as x axis and y axis.
The standard equation for a straight line is y mx c where m is the gradient. In a simple line diagram we plot each pair of values of t y y representing the time series at the time point t in the ty plane. If the tangents have to be parallel to the line then they must have the same gradient.
Drawing a sign diagram.
Horizontal line the x axis positivenegative signs indicating that the graph is above and below the x axis. They are particularly useful for situations like illustrating changes that happen over a period of time or other variables. It is the general procedure to use single line diagrams for representing three phase systems. Plot line diagram math.
