A。 如何使用此在线计算器
重要! 该数学或科学计算器使用[DEG]意思是度模式。这于三角计算使用。例如：COS(90)意思是 cos (90) 意思是 g相同.。. 模式是全世界学生通常使用。
使用科学计算器执行三角计算时需要小心。有些计算器使用[RAD]弧度模式或者Radian (1 RAD = 57,296°)作为标准设定。[RAD]（弧度）模式，通常用于高等教育，例如: 纯物理学。按[RAD]改变 [Radian] 弧度模式。
A1。基本按键功能
AC 全清键 （AC）按键清除除存储器内容外的所有数值
← 按键“退格”键时清除最后一
F2 按键访问权限：反三角sin-1 （arcsin），反餘弦 cos-1 （arccos），反正切 tan-1 （arctan），倒三角比例csc（正割），sec（正割），cot（余切），立方根，自然对数（ln），阶乘（！）和欧拉数（e）
A2。算术按键功能
= 按键执行计算使用
1 = 1
+ 按键执行加法使用
1 + 1 = 2
- 按键执行减法使用
6 - 2 = 4
× 按键执行乘法使用
10 × 10 = 100
÷ 按键执行除法使用
8 ÷ 4 = 2
. 按键执行类型小数使用
8.2 + 1.8 = 10
( ) 按键执行括号使用
1 × (3 - 1) = 1 × 2 = 2
A3。乘幂和根计算器按键功能
^ 按键执行乘幂使用
2^3 = 2 × 2 × 2 = 8
√ 按键执行根号使用
√(144) = 12
3√ 按键执行三次幂使用
3√(8) = 2
A4。百分比和阶乘按键功能
% 按键输入百分比符号使用
45% = 0.45
! 按键输入阶乘符号使用
3! = 3 × 2 × 1 = 6
A5。几何和对数按键功能
π 按键输入phi （派）常数使用
π = 3.141592653589793
e 按键输入欧拉常数使用
e = 2.718281828459
log 按键执行以10为底的对数使用
log(100) = 2
ln 按键执行自然对数使用
ln(e) = ln(2.718281828459) = 1
A6。三角按键功能
A6.1 三角按键的基本功能
sin 按键执行计算正弦使用
sin(90) = 1
cos 按键执行计算余弦使用
cos(90) = 0
tan 按钮执行计算切线使用
tan(90) = Infinity!
A6.2 反三角按键功能
sin⁻¹ 按键执行计算反正弦使用
sin-1(0) = 0
cos⁻¹ 按键执行计算反余弦使用
cos-1(0) = 90
tan⁻¹ 按键执行计算反正切使用
tan-1(45) = 88.726969979943
A6.3倒数触发比例按键功能
csc 按键执行计算余割使用
csc(60) = 1.154700538379
sec 按键执行计算正割使用
sec(45) = 1.414213562373
cot 按键执行计算餘切使用
cot(60) = 0.57735026919
提示：欧拉数e符号在屏幕上
上面的在线计算器使用指数精度。您可以使用以下科学符号找到结果。
B。键盘功能
您可以使用键盘输入数字和算术运算符
0 1 2 3 4 5 6 7 8 9 . 按键可以输入数字使用
+ - * / 按键可以输入算术运算符使用
Backspace 按键可用于清除最后一位数字使用
Enter 按键可用于执行计算（相等）使用
C。计算历史记录
查看和用历史记录执行继续或者新的计算，请按下在计算器的屏幕。
D。科学计算器是什么？
科学计算器是一种使用解决数学，工程和科学的计算。 这个计算器是为您日常活动简单的科学计算器。
另外，普通的计算器通常只能执行算术计算，即加，减，乘，除，并且可以用百分比之类的其他计算来完成了。

在线计算器
计算器（calculator ；counter）一般是指“电子计算器”，该名词由日文传入中国。计算器能进行数学运算的手持机器，拥有集成电路芯片，但结构简单，比现代电脑结构简单得多，可以说是第一代的电子计算机（电脑），且功能也较弱，但较为方便与廉价，可广泛运用于商业交易中，是必备的办公用品之一。
