Hi There, I have been having a go at this Isaac physics question and I am a bit stuck. The question : https://isaacphysics.org/questions/d...c-d7589d89f7ce

I am on part d and am currently confused as to why we answer is not just when d/dx ((sin x) / x ) = 0 , does this not indicate a maxima (as its a stationary point, or am I missing something.... Many thanks, all help appreciated!
