To find the limit of cos(x)/x as x approaches 0 from the left side, we can use L'Hôpital's Rule. Taking the derivative of both the numerator and denominator, we get -sin(x)/1. Evaluating this at x=0, we find that the limit is equal to 0.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
