Hello, i stumbled across a function that does not want to plot regularly.
The translation: The tension U(t) (in volts) measured across a resistance in a electric circuit is given by U(t)=cos(2t)*U*e^t/10.
a. Plot the graph of y=U(t)
b.Calculate the limit t->infinity and acquire the horizontal asymtote of the graph of y=U(t).
c. Calculate the intersecting points of the graph of U with horizontal asymptote (dont ask me how, while how can a function intersect with its own asymptotes??).
So the question actually is how to graph this function?
Maybe then i can make up from that how the function intersects with its own asymptotes.
