For the trig I used both a cast diagram and a sin graph to help me answer it, will that be accepted? I got the answer right but i didnt make it obvious that i used CAST
Omg I used both too. I drew the CAST and then used the graphs to double check my answers. Hope it is okay
SOMEONE PLEASE ANSWER, FOR THE MINIMUM VALUE OF P MY X VALUE WAS CORRECT HOWEVER I DID NOT SUB IT INTO P HOW MANY MARKS WILL I LOSE? LOOKING AT THIS MARK SCHEME IT SEEMS LIKE ONLY 1 BUT I CAN BE WRONG

I think I've lost 5 marks max, a few on question 1, even though I did ar^(10-1) - ar^(9-1) I got -0.025 and the other for the proof of the perimeter even though I got y= 500/x -x/12(4Pi +3root3)

For q9 x= 16.63, did the x need to be to the nearest metre or something, I thought they just wanted the perimeter to the nearest meter but can't remember what the question said
