    Honestly can't remember. If it was <= 360 then there would be 5 values, but I'm pretty sure it was < 360
    it was <= 360, I triple checked because I thought you could only get 4 solutions but I got 5

    it was <= 360 so 360 is a value.

    I got exactly the same as that
    I got 0.66 and 0.193... How accurate do you think they'll mark it?

    swear its only 2 values? because if i did it right i got 4sinx - 1 = 0

    so isn't it just sin^-1 25

    or is there another step i missed? x
    Sinx(4sinx-1)=0
    Sinx= 0 so that is 0,180,360
    4sinx=1
    X= 14.something
    180-14.something = 165.something

    I forgot to put 180 as a value (Stupid me -_-) But got the other 4 right, would I only lose a mark? And I also did the working out for the f(5+h) question right but in the end I used the operations wrong, how many marks would I lose?

    Overall I found it easy, I just made some silly mistakes. Probably lost like 6-8 marks altogether.

    Also if anyone was wondering, I got 0.6 as my log a and 0.21 as my gradient. In the end I got y = 3.891 x 10^0.21t

    A preferable line of best fit is where you would have an equal amount of points that weren't lined through on each side. I had 3 points on each side that were unlined which made it appropriate for me to use as my line of best fit.
