Anyone know how the Multiple choice for that how many number of root for cx^2 +ax+b works I got 2 real root cause it’s just guess work lmao

0 roots i think? i remember b=c coming up, and then doing some ******** to deduce a^2 - 4bc was negative. swear i remember a = -(b+c)/2 as well but idk lmao

pretty sure the key idea was just to utilise the fact that cos(90-x) = sin(x).

i dont remember the exact expression, but there were two brackets multiplied iirc, one was (1 - cos^2(2x-60)) and the other (3-cos(150-2x))

by applying the identity to the left bracket, you get (1-sin^2(150-2x)) = cos^2(150-2x) which leaves the expression in a form previous to the prior part, but with something to the power of 4 instead?

anyways i got an answer of 16^4 = 4^8 = 2^16. If you know the expression, I could explain it probably, but i'm pretty confident it was maximised when cos(150-2x) = -1.

omd yeah that makes sense i shioldve seen that. i got the right answer just by inspection p much but idt they'll give me many marks. at least 1 out of the 6 but idk it could also be 6/6 if I'm v lucky.

what did you get for square number one

what did you get for square number one

it was the one ending with 25 iirc

yh me too but did you guess? i guessed it looked like the only good option

nah i looked at the last digit. either 1,4,5,6,9 or an even number of zeroes at the end. all the options can be eliminated except the one ending with 5

I got the same I think except for J which I guessed, what was question C though cos I forgot what I chose for that?
