I have to differentiate the following function using the Product Rule:
f(x) = (cos x)e^-x sqrt 3
Here are my workings so far:
g(x)=(cos x) h(x)=e^-x sqrt 3
f ' (x) = g ' (x) h(x) + g(x) h' (x)
= (-sin x)e^-x sqrt 3 + (cos x)-e^-x sqrt 3
From here I do not know how to proceed further and am not sure whether above working is correct.
