I have found where I went wrong on question 10.
1. I can't simplify (2/4sqrt 2 I am assuming I wrote)
2. I can't square my unsimplified answer 4 sqrt 2 properly either (I am thinking that turned into 64.)
Hopefully they will have pity on me and I will get 2/3 not 1/3, because I am thinking I found tan x properly, just in an unsimplified form. I sure bloody hope so anyway.
So annoyed at myself. Last year I wrote d(6x^3)/dx=12x^2 and I wanted so badly to not repeat something similar, this was near the end of a question but so if I am lucky I will get 2/3 for method. Sure hope so...
so 37/38 plus I am not at all confident on the slope field. wooo.
Oh and my internet keeps going on and off, really want to kick it. None of the random neighbour's wireless signals I can pick up it won't let me connect to either. ISP said it was their bad, stupid twits.
Edit: I think I drew the slope field stuff right then ^_^
Edit: I forgot about the dilation of tan on the slope field xD so 36/37 =[
