SHIFT,ALPHA,MODE是功能键
X!阶乘
X-1 是1/x
公式nPr P是指排列,从N个元素取R个进行排列(即排序).
公式nCr C是指组合,从N个元素取R个,不进行排列（即不排序）.
d/c显示分数,ab/c显示代分数
log,10x,ex,ln,(-) 对数,指数
[.,]度分秒
sin,sin-1,cos,cos-1tan,tan-1三角函数
Ans清零
Mod 显示 x/y 的模数或余数.此按钮为二进制运算符.例如,计算 5 除以 3 的模数,单击“5 MOD 3 =”,结果为 2.
其他的记不到了.
我手头现在没有计算器对着看
其实还是看说明书最好.
希望对你有帮助~~
