    Hi everyone,

    Can anyone tell me how to sketch a graph of for example
    x(t)=(2+sin(2*pi*t))sin(20*pi*t) and similar formulas

    and thanks.

    Start by finding the roots of the function (there'll be plenty!), then mark those on your graph, look at the starting value for t=0, it is zero or 1 or 2 or...? Look at maxima and minima, where do they occur? Mark these on your page, then draw the hopefully obvious curve between them.
