„Transformação de coordenadas

Pressionando [ 2nd ] [ RP ] exibe um menu para converter coordenadas retangulares para coordenadas polares ou vice-versa. Veja Exemplo 40~41.

Coordenadas retangulares

Coordenadas polares

x + y i = r (cosθ+ i sinθ)

(Nota) : Quando usar essas teclas, assegure-se de que a calculadora está ajustada para a unidade de ângulo que você quer.

„Probabilidade

zPressionando [ PRB ] exibe o menu de probabilidade. Veja Exemplo 42~46. Com as funções seguintes :

nPr Calcula o número de permutações possíveis de n items tomando r a cada vez.

nCr Calcula o número de combinações possíveis de n items tomando r a cada vez.

!Calcula o fatorial de um n inteiro positivo especificado onde n ≦ 69.

RANDM Gera um número randomico entre 0 e 1.

RANDMI Gera um valor inteiro rândomico entre dois inteiros especificados, A e B onde A ≦valor rândomico ≦ B

„Outras funções ( x–1, √, X , x 2, ^ )

zA calculadora também provê funções de recíproco ( [ x –1] ), raíz

quadrada ( [ √ ] ), raiz universal ( [ X ] ), quadrado ( [ x 2 ] ) e exponenciação ( [ ^ ] ). Veja Exemplo 47~50.
