>To apply l'Hospital's rule here you need to know the derivative of the sine function.
But I do know the derivative of the sine function. So, you could argue that applying L'Hospital's rule makes no sense. But actually, it's not mathematically incorrect, it's just redundant and arguably stupid - I'm considering the derivative as a given, and then using a roundabout method to use that derivative to calculate itself.
That's the nice/annoying thing about L'Hospital's rule, depending on whether one is a brainlet - you can memorize some identities and derivatives and then brute force your way through a bunch of limits without understanding wtf is going on.

Anon, what the fuck are you doing. You failed the easy A class
