Solution for...
A wire length 4 meters is bent to form a rectangle. Find the measurement of its sides so that the rectangle has a maximum area.
Solution:
Perimeter:
2a+2b=4………(i)
a=(4-2b)/2
=2-b………(ii)
Luas:
A=ab………(iii)
Substitute (ii) into (iii)
=(2-b)b
=2b-b^2
Untuk dapatkan maximum area,
dA/db=2-2b
dA/db=0
2-2b=0
b=1
a=2-b
=2-1
=1
(d^2 A)/(db^2 )=-2
∴ maximum area with a=1,b=1.

INTEGRATION
Why do we need to study Integration?
The Petronas Towers
of Kuala Lumpur
To find this direct relationship, we need to use the process which is opposite to differentiation. This is called integration (or antidifferentiation).
The processes of integration are used in many applications.
The Petronas Towers in Kuala Lumpur experience high forces due to winds. Integration was used to design the building for strength.
Sydney Opera House
Wine cask
Other uses of integration include finding areas under curved surfaces, centres of mass, displacement and velocity, fluid flow, modelling the behaviour of objects under stress, etc.
