QUESTION ONE

Find the area of the part of the surface z= that lies above |x|+|y|<=1

Area bound by any function is given by

But ===

Boundary conditions;

Line a:

b:

c:

d:

From the graph, for all values of x such that , |y|

to

Therefore;

Using Maple software,

Since the surface is symmetrical about y-axis,

Total area=

QUESTION TWO

Find the exact area of the surface

-2×1, -1y

Area bound by any function is given by

Therefore;

Boundary conditions

X varies within the range -2×1

Y varies within the range -1y

Solving by maple software,
