To find the detailed algorithm, I don t have a calculator, I use a window7 computer calculator. Calc

Win7 comes with a calculator with a variety of modes, and I still haven't found the calculation button for the inverse trigonometric function after I switched to the scientific type. Here's how to find the scientific type.

Click on the scientific type and it will look like this.

I'm sorry I didn't find the button for the inverse trigonometric function, though. If you have Excel on your computer, you can use the relevant mathematical formulas in Excel to calculate it. I use the Excel version of 2010, which may be a little different from yours.

Below is a screenshot of my calculation process.

1. Enter the relevant data in Excel and calculate the result of 1+(k 2-1)t d.

<>3. In the pop-up interface, enter trigonometric function in the search box, and click go next to it, and then find the function ACOS in the search results below (ACOS is also arccos, which is the inverse cosine function in the inverse trigonometric function mentioned above, the result is radians, to convert it into degrees, please divide the result by pi (pi = then multiply by 180) and click OK. As shown in Fig.

4. Click the button next to the input box in the pop-up interface, then click the cell where the first step calculation result is located, then click the button with a small arrow down next to the dialog box, and click OK in the pop-up interface, as shown in the following figures:

<> then through the radian angle conversion formula in the third step, you can calculate yes.

The calculator comes with inverse trigonometric functions. Note that clicking on "inv" is fine

The so-called "correct" is just my personal opinion. If any friend has a more correct method, welcome to reply.

Do you think you can turn on the computer machine and type 15+16 with the keyboard?

Or, click 15+16?, with your mouse on your computer

Of course, that's fine. However, unless you're careful, there's a good chance you'll make the wrong number when you type on the keyboard or click on the mouse.

What if you want to calculate 3 2 + 5 6 + 7 * 9? Friends who know how to use calculators know that they use M+. But in fact, it's easy to make mistakes.

Or you need to calculate (45+47)*(15-7).

The correct posture is:

You won't copy the results or type them into the software you want to use, right? On the Windows Calculator screen where the results are displayed, press Ctrl+C....

You can still copy-paste yo.

Well, it's very simple, maybe you've already done it this way. That shows that we are heroes and see the same thing!

One of the advantages of this operation is that it can reduce input errors and improve the accuracy of calculations.

Second, the input speed is relatively fast, and there is no need to use M+ to improve the speed of calculation.

Actually, if you have Excel installed, then I would say that Excel is definitely a better calculator.

But if your calculations aren't very complicated, you're not repeating similar calculations, or you don't have Excel installed, then this method is definitely a good way to go.

Say goodbye to you"m+"!

DAO 3rd Edition Calculator App. The user has the right to press the Win+R key to open the "Run" dialog box, enter, press the Enter key to open the calculator that comes with the system.

2. The calculator that comes with the system has different viewing forms, click the "View" menu, and you can choose from:

Standard: The simplest calculator, which mainly completes four operations.

Scientific: Mainly complete mathematical operations, such as trigonometric functions.

Programmer: can complete computer operations, such as logic and, or, non, base conversion, etc.

Statistically informative: data that is mainly used for statistical calculations.

Take the calculator that comes with the win10 system as an example.

1.Open the calculator that comes with your computer, and the default is the standard mode.

2.Click on the menu in the upper left corner to switch to Scientific Calculator.

3.First, enter the base number, then press the x y key (some calculators are , then enter the exponent, and then press the equals key.

For example, to calculate 12 to the 34th power, the keys are as follows:

Result: 4922235242952026704037113243122008064

When it comes to using a calculator, most people's reaction is like, calculator, who wouldn't use it?

But do you really know how to use a calculator? Below I will show you how to use the counting calculator for you

Is it the same as Capy?

AC is the abbreviation of ALL CLEAR, C is the abbreviation of CLEAR, and CE is the abbreviation of CLEAR ENTRY;

Generally speaking, there are only C and CE on the calculator, and C means Clear All, and CE means Clear Current Input; For example, if you want to enter 5*7 and the result is 5*8, then you can select CE and then enter 7 to get the result you want; On the other hand, if you find that the first one you entered was wrong, you might select C and re-enter it.

What the hell is it?

GT is short for Grand Total, which is the sum of all input numbers.

If you want to calculate the value of 15*5+36*3, then you can enter , gt , = and this gives you 183

What the hell is it?

mu is short for mark-up and mark-down.

The mu key, also known as the tax key, is used to calculate the tax rate. Such as:

1. Addition: Enter A+B and press Mu, the calculation formula is: 100+A B 100;

2. Subtraction: press mu after entering a-b, which is often used to calculate the rate of change, and its calculation formula is: (a-b) b 100;

3. Multiplication: press mu after entering a b, which is often used for the calculation of markup, and its calculation formula is: a + a b%;

4. Division: press mu after entering a b, which is often used for the calculation of the marked price, and the calculation formula is: a (1-b%), when pressing the mu key again, you can get the profit value, and the formula is: a (1-b%)-a.

I believe that after reading this article, your understanding of calculators is different again, and you have surpassed many people.

1) 1 7 = Cycle knots are 142857

2 7 = Cycle knots are 285714

3 7 = Cycle knots are 428571

4 7 = Cycle festival is the first cherry blossom 571428

5 7 = Cycle knots are 714285

6 7 = Cycle knots are 857142

2) According to the above calculation, the decimal part of the quotient of 5 7 is a cycle of 6 numbers, which are arranged in a cycle according to the order of filial piety and 714285, 34 6 = 5....4

So the 34th digit is the 4th digit of the 6th cycle section, which is 2

1-2 2+3 3 (accurate ==.)

2 3- 3 2- 5 Keep three significant digits ===

125-2 5 (to the nearest decile) = 5 5-2 5

I know I won't adopt me, but I still have to scold: Emma landlord, you are too lazy!

Select the scientific type in the option to click "View" - "Scientific type", the pink word on the left is square in the middle, cube, to change the calculator to the scientific type, there are two buttons, which are x 2 and x 3, which mean squared, respectively
