Thanks for the video!! Much appreciated :)
Great video. I think that technically you are not allowed to use l'Hopital for this limit as you have to use the same limit to prove that the derivative of sinx is cosx, so a purist may say that you have to use series expansions or clever geometry.
doesnt a series expansion rely on the derivative of the function which uses the limit as well though
please produce more
when u mean for stem students. could questions like this appear if u were applying to Mathematics at university
because i doubt for a cambridge mathematics interview will have a straight forward question aas this.
Can you do one for probability?
