1)prove that
tanx + cot x = 2cosec(2x)
2) a population of deer is introduced into a park. the population 'p' at time 't' years after the deer have been introduced is modelled by :
P = 2000a^t / 4 + a^t
'a' is a constant. given that there are 800 deer in the park after 6 years, and 'a' is 1.1776,
use the model to predict the number of years needed for the population of deer to increase from 800 to 1800.
