Determine the time function corresponding to the output s function
To obtain the output as a function of time we need to find the time
function that will give the particular output s function that we have
obtained. Tables of s functions and their corresponding time
functions can be used; Table 3.1 is a table of commonly encountered
functions. Often, however, the s function output has to be rearranged
to put it into a form given in the table.
