(XOR), negation (NOT), and negation of exclusive logical sums
(XNOR). See Example 43.
5 Mode 3 - CPLX
Complex mode enables you to add, subtract, multiply, and divide
complex numbers. See Example 44. The results of a complex
operation are displayed as follow :
Re Real value
ab Absolute value
6 Mode 4 - VLE
Variable linear equations (VLE) mode can solve a set of
simultaneous equations with two unknowns as follows :
a x + b y = c
d x + e y = f, where x and y are unknown.
In VLE mode, you just enter each coefficient ( a , b , c , d , e , f ) in
the correct order, and the calculator automatically solves for x, y.
See Example 45.
7 Mode 5 - QE
Quadratic equations (QE) mode can solve a equations as follows :
a x
In QE mode, you just enter each coefficient ( a, b, c ) in the correct
order, and the calculator automatically solves for all x values.
See Example 46.
