# OCR MEI - C1 - 13th May 2015 watch

1. who's excited for FP1 tomorrow
2. I can't believe I got question 1 wrong
I divided by (x+y) then divided by Pi because you're dividing a divide by pi it would go on top to make (Pi*A)/x+y
I thought that was right, but all my friends said they divided by pi x+ y . I saw I could do that but though it didn't look right
3. Just done OCR C1 exam. Was all good other than Q6. Done a stupid mistake on circle question at the end. Hoping for the best!
4. Guys for one of the questoms which asked you to prove it doesn't cross the x axis, I didn't do the discriminant as I was checking answers and only just saw that part, so I explained it, saying how it's minimum y point is above the x axis therefore meaning it doesn't intercept it etc. Would that get me any marks?
5. (-2, 1) was definitely the minimum point, right? Not (-6, 1)? I took a gamble on that one... What did you all get for 'k' on the last question then?

Show the turning point, then state it's a minimum as its a positive parabola
