Hey all,

so, I have encountered a problem that asks me to sketch the graph of the following: f(x) = sin(x)cos(12x). I know how to sketch them both separately, but what is the procedure so that I can do this properly without using a calculator?

another type of problem asks me to sketch something like this: 4cos(x)-3sin(x). I have the same issue here as I would the above example.

thanks in advance for your help!
