Here is a typical sinusoid:
The most general mathematical formula for a sinusoid
\(x(t)=A \cos(2 \pi f_0 t + \phi)\)
The goal of this demo is to learn how to sketch a sinusoid given
its formula and to write the formula of a sinusoid given its plot.
is a quick tutorial on how to
sketch a plot from an equation, and
is a tutorial on going the other way.
is how to plot sines in MATLAB.
will take you to
GUI (graphical user interface) that tests your
ability to go from plots of cosine waves to equations.
