um they made a few errors. like for probability, their working out was right but they forgot to multiply by 2

BUT OMG SUCH A RELIEF TO SEE THE SOLUTIONS I was so scared about careless mistakes
Forgot to multiply by 2 too !

7 is b because x=pi/2 is not considered a solution since tan(pi/2) gives no solution.
so the only solutions are from tan=-2 (two solutions)

so sad cuz i put down 3

For once my stupidity has actually paid off! I thought "meh, no idea how to solve" and drew a graph containing the tan thing and sin thing (don't judge me okay I've already said I'm a dumbass). And then looked to see all the places they intersected. By pure coincidence it's two. Woohoo!

Already knew i screwed up the LOAN REPAYMENT question Lost a mark on MCQ, a mark on that limiting sum to with the DRUG question which i couldn't comprehend, mark on the derivative curve and mark off for finding point 'P'

Hopefully ~93 raw
