substituted in X.
2)
Calculation
conditions
in
matrix
operation
are
as
follows
(with
m
n
in
the
matrix
operation
and.
the
result
is
atrix A as
(i,
j)
and
matrix
B
as
(m,
n)).
a)
Addition
and
subtraction
Substituted
in
X
when
i=
m
andj
=n.
b)
Multiplication
Substituted
in
X
when
i=
m.
c)
Determinant
Substituted
in
X
when
i=j.
d)
Inverse
matrix
Substituted
in
X
when
i
=
j
and,
moreover,
when
the
determinant
is
other
than
0.
e)
Simultaneous
linear
equations
Substituted
in
X
when
the
three
conditions
of
i
=
j,
determinant
is
other
than
0,
and
j
=
m
are
realized.

error
will
occur
if
these

are
not
satisfied.
3)
Care
is
required
in
matrix
operation
since
there
will
be
times
when
accurate
results
cannot
be
obtained
because
the
determinant
is
near
zero
or.

are

4-3 Complex Number Calculations
Complex number calculations encompass arithmetic operations, and to obtain
absolute values, arguments, squares, cubes, square roots, and cube roots,
The complex number operation starts from the software menu by pressing the
Comp [C] key. The following will be displayed first. :
re Subtraction
@®..... Multiplication
..... Division
O)..... Absolute value
M..... Argument
GI ..... Square
AJ... Cube
..... Square root
BA..... Cube root
Ge ..... New input
® Arithmetic Operation
Example 1:
Perform the following calculations.
@® (2+3i) + (3-23) @4—- (8+2i)
® (1+2i) x (3-23) @ (2-31) + (14+ 2i)
