Calculus 1: L'Hospital's Rule (11 of 25) Example 10

In this video I will use L'Hospital's Rule to solve limit-as-x-approaches-0 of {[cot(x)][som(2x)]}.

Next video in the series can be seen at:

sir why is cot (0) is equal to infinity while sin(o) is just equal to zero. pls sir

You could have just expand sin(2x) into 2*sinx*cosx.
Then you would get lim2(cosx)^2 and when you plug value for x, you get 2

Nice video but do you know you shouldn’t pronounce the “h” - L’Hôpital was French.
