Example 3: (1 + i)
4
+ (1 - i)
2
= -4 - 2i
(Complex Result: a+bi)
1 (i) 4
1 (i)
Note
• When raising a complex number to an integer power using the syntax (a+bi)
n
, the
power value can be within the following range: -1 × 10
10
< n < 1 × 10
10
.
Example 4: 2∠45 = √
2 + √2i
(Angle Unit: Degree, Complex Result: a+bi)
2 – [Complex] > [∠] 45
Example 5: √2 + √2i = 2∠45
(Angle Unit: Degree, Complex Result: r∠θ)
2 2 (i)
Example 6: To obtain the conjugate complex number of 2 + 3i
(Complex Result: a+bi)
– [Complex] > [Conjugate]
2 3 (i)
Example 7: To obtain the absolute value and argument of 1 + i
(Angle Unit: Degree)
– [Numeric Calc] > [Absolute Value]
1 (i)
– [Complex] > [Argument]
1
(i)
