welll theres a much easier and quick way wherevery u see radicals as here........just take square on both sides ....then employ either logarithmic differentiation or implicit differentiation.....its going to make the algebra hell easier

see did you get the answer from part (i) its 13sin(x+67.38)
so you do 13sin(x+67.38)=11
sin(x+67.38)=11/13
angle=57.38
2x+67.38=122.2 from 180-57.38
2x=122.2-67.38
x=27.4
other one is 360+57.38=417.8
x=175.2

Solve the following question:

10 The number of birds of a certain species in a forested region is recorded over several years. At time
t years, the number of birds is N, where N is treated as a continuous variable. The variation in the
number of birds is modelled by
dN
dt
=
N(1800 − N)
3600
.
It is given that N = 300 when t = 0.
(i) Find an expression for N in terms of t. [9]

I can't seem to decompose the fraction into its partial fractions correctly.
