金融计算器使用技巧2-FINANCIAL CALCULATOR–数学计算

Posted on 10 May, 201111 May, 2011 by admin

1 开平方
已知面积900,已知长宽比2:3,问具体长宽

2X * 3X=900, 即6*X的平方=900
即900/6后开平方=求150的开平方结果

使用方法:
1 输入150,按桔红色键+“-”即开平方键,显示12.25即结果
12.25*12.25=150.06约等于150平方米
即宽为24.5米,长为36.75,面积为900.375


2 开立方

You can compute the cubic root of 27 using the following keystrokes:

27
orange shift y^x (multiply key)
3
orange shift 1/x (divide key)
=

You can also use the x√y (x root of y) key of the math set of keys. Touch the following keys:

blue shift math (minus key)
27
x√y
3
=
注意进入MATH专项界面后,
The y^x function appears 2 places on the math set of keys. The one under the multiply key does not work, the one under the x root y (row2, column 4) does. 程序BUG,The next release will fix the problem
