A farmer wishes to build a rectangular sheep pen with a 160m fence,using one side of an existing shed as the side.The shed is also rectangular of measurement 20m X 20m.

(a)Find the measurement and the area of the sheep if one side of the existing shed is used as the width of the sheep pen.

(b)By using the fence of the same length and using the width of the shed as part of the width of the sheep pen,find the length and width of the sheep pen with maximum area.

(c)If two sheep pens of the same size are build adjacent to each other,find
(i)the length of the new sheep pen if one side of the shed is used as the width of the sheep pen.
(ii)the length and width of the sheep pen,which is adjusted so that the enclosed area is maximum.

(d)Find the maximum enclosed area if the same fence is used to construct three rectangular sheep pens.

I kind of know how to start it off:

The Inverse Trig. Function for cos^-1 is -1/ sq root (1-x^2).

So it would be [-1/ sq root(1-cos^2(x))] * d/dx cos(x). d/dx cos(x) is equal to -sin(x).

So then you would have sin(x)/ sq root(1-cos^2(x)).

First off, am I right. Second, isn't my answer an identity?

Suppose a system"A" is there whose axis is having "+n" points on its axis & another system "B" identical to system "A" is there on the opposite side of system "A" but apart from system "A" having same "+n" points on its axis.Then there would be an axis joining "+n" of system "A" & "+n" of system "B".What would be the center of such an axis joining "+n" of system "A" & system "B"?
Take "+n" as +1.
