I submitted it, from exam papers called STEP maths (the entrance exam taken for Cambridge Uiniversity Maths degree), this is taken from STEP Maths 1 2016 Q11
Genuinely, hats off to you for ploughing on with the question. You are at a disadvantage with these questions being advanced and specialised in your field sometimes, as oppposed to, as you mention at the start of video knowing some basic high school equations, that students sitting this exam will have known. The standard projectile SUVAT formulas and equation for the trajectory of a projectile rather than deriving them from first principles like you did. Then later on they will have known the various formulas for cos2x etc. This is classic STEP mechanics question, fairly basic mechanics, then proceeds to include calculus, trig and some messy algebra. Hope it does not put you off doing other mechanics questions!! Thanks again.
I think you and I might have very different ideas of what the difficult or annoying parts are! I thought that deriving some of these equations wasn’t an issue at all, and some of the initial parts of this problem weren’t too bad. But towards the end it essentially just turns into tedious algebra which makes anyone prone to errors and doesn’t really demonstrate anything interesting mathematically. I wouldn’t have known that it would turn into that without going through the whole problem though. Keep up the submissions! Even if they are somewhat more mechanics or physics related than mathematics.
@@mathoutloud Hi, it less about difficulty and more the fact if you went straight to trajectory formula, you get to first part in a few lines. Then after the differentiating spotting the trig formula leads you to x=htanα quickly, just save times. As you said after that there is a lot of grinding algebra. The purpose for this I have read given by exam board is "testing the ability of students to work accurately and quickly", make of that what you will and it's usefullness. In A Level maths most students as well as doing pure maths will do mechanics or statistics as well. Keep up the good work.

Do you know where they got this question from? love ur vids btw
