Algebra
X(t) = amount of pesticide in the plant,
Y(t) = amount of pesticide in the soil,
R(t) litre = amount of pesticide applied to the plant
t = time in years
A typical model is obtained from input output frequency domain analysis
X/R=(S+3)/((S+3)(s-2)+2)
In a pristine orchard, the initial data is X(0)= 0, Y(0)=0, because the plant and the soil initially harbor no pesticide.
Represent the given transfer function X/R in the form of partial fractions.
one senior student has found the solution for X(t)/R(t) and he states that, X/R=e^(-βt )[cosh(αt) +5/√17 sinh(αt)] were Α=√17/2,β=1/2, Initially 2 litres of pesticides were sprayed on plants.[R(0)=2 litres]
Given,R(t) = 2/t^(2 )+1 Find the amount of pesticides in the plant after six months.

Pesticides are used by farmers to product their crops from insects. A farmer sprayed pesticide on his tomato cultivation Assume unknown amount R(t) litres of pesticide were sprayed on the soil. Pesticides spayed on plants have a certain outflow rate in to the soil, and conversely,pesticide in the soil has a certain uptake rate into the plants.repeated applications of the pesticides are required to control the insects, which implies the pesticide levels in the plants varies with time. Quantize the pesticide spraying as follows;
x(t)=amount of pesticide in the plant,
y(t)= amount of pesticide in the soil,
R(t)=amount of pesticide applied to the plant
t=time in year

X/R= (s+3)/((s+3)(s-2)+2)
In a pristine orchard,the initial data is X(0)=0,Y(0)=0 because the plant and the soil initially harbor no pesticide.Represent the given transfer function (X/R) in the form of partial factions.

As Alberta's reserves of light crude oil began to deplete,so did the production. Alberta's light crude oil production totaled 37.3 million cubic metres from 1997-2005
This production has continued to decline each year from 1990 and only 21.7 million cubic metres were produced in 2005
use the above scenario to define a sequence or a series to predict possible initial production in year 1990 and the trends in the use or production of the resource over 1990-2005 year period.
Hence,predict the production of year 1990.
Assume that the production of light crude oil declines at the rate of 30% of its total production of the previous year from 1990. Define a sequence or a series to predict possible initial production in year 1990.
