Conversión de la unidad

z

Las calculadoras tienen una característica incorporada de

conversión de unidad que le permite que convierta los números

de unidades métricas a las unidades inglesas y viceversa. Vea

Ejemplo 51.

1. Entre el número que usted quiere convertir.

2. Presionar [ 2nd ] [ CONV ] para mostrar el menú. Hay 7

menúes, cubriendo distancia, área, temperatura, capacidad,

peso, energía, y presión.

3. Use el [



] [



] para desplazar a través de la lista de

unidades hasta que un menú de unidades apropiado sea

mostrado, luego [

base de ese número presionando tecla [ NEG ] para bases

non-decimales. Vea Ejemplo 60.

Operaciones aritméticas básicas para bases

z

La unidad le permite que usted calcule en la base del número de

otra manera que el decimal. La calculadora puede adicionar,

restar, multiplicar, y dividir números binarios, octales, y

hexadecimales. Vea Ejemplo 61.



Operaciones lógicas

Operaciones lógicas son ejecutadas a través de productos lógicos

(AND), negativo lógico (NAND), sumas lógicas (OR), sumas lógicas

exclusivas (XOR), negación (NOT), y negación de sumas lógicas

exclusivas (XNOR). Vea Ejemplo 62.

Mode 3 - CPLX

z

Modo complejo le permite de adicionar, restar, multiplicar, y dividir

los números complejos. Vea el Ejemplo 63.

Los resultados de una

operación compleja son mostradas como sigue:

Re Valor Real Im Valor Imaginario

ab Valor Absoluto ar Valor del argumento

Mode 4 - VLE

Modo de ecuaciones de variables lineales (VLE) puede resolver una

serie de ecuaciones simultáneas con dos números incógnitos como

sigue :

a x + b y = c

d x + e y = f, donde x y son incógnitos.

z

En modo VLE, usted apenas entra cada coeficiente (

a

,

b

,

c

,

d

,

e

,

f

)

en el orden correcto, y la calculadora resuelve automáticamente

para

x

,

y

. Vea Ejemplo 64.

Mode 5 - QE

Modo de ecuaciones cuadráticas (

QE

) puede resolver ecuaciones

como sigue :

a x

2

+ b x + c = 0, donde x son desconocidos.

z

En modo QE, usted entra apenas cada coeficiente (

a

,

b

,

c

) en el

orden correcto, y la calculadora resuelve automáticamente para

todo los valores x. Vea Ejemplo 65.
