Example 11:
If = 2 + 3 , = 3 + 2 , = + , ∈ ℝ ,
Find the value of | + |. The Keystrokes for this are,
Cq(Abs)2+3b+3+2b=
| + | = 5√2
Given = what is W in terms of a and b ?
C(2+3b)a(3+2b)=
12 5 12 − 5 5 + 12
= ( + ) ( + ) = +

Given that = − , the argument of W (in
13 13
radians) is given by,
Cq(CMPLX)1a17p7bR
