i got 8/3 ln 5


Yeah sorry, 8/3 was getting the question confused
What did people get for the implicit differentiation, I got 11/8?
Oh wow, that was a really nice paper all things considered :biggrin:!

yes!!i got that for 11/8 for the gradient of P too!
Did anyone get -4/5 on the end of the differential equation
Thought I did well, which probably means the grade boundaries are going to be stupidly high.:tongue:

That's correct I think :smile:
c= 1 for the differential?
on the trig question r(cosx-angle) did anyone get r=root29 and angle +1.19??? Anyone?? Think that's what I put... And then x at max value 5.09 or something?
