Choose a CASIO scientific calculator

Fertilizer and water don't flow into outsiders' fields, and if you don't ask me this question, I'm simply at a loss.

Give it points, quack.

This is the official website 1l is talking about graph programming calculators, and graph programming calculators focus on drawing. (Like this one.)

The 991es plus is currently the strongest in Casio's functional science type, so you can buy this one and use it until college. Cost-effective.

If you want to display an image on the screen, you need to use the kind that 1L says, but the graphics programming type is more professional, and it is not cheap.

The function science calculator can't display the image directly, you need to set up the function, and then set the definition field, and define the value interval of the field, and then the calculator will automatically build a table, you can trace the points according to the list, we draw the function image is drawn like this, it is very convenient, much more convenient than using the calculator to assign a single press.

If you don't understand, I'll text you to tell you, I just bought it today.

Also, you must give me a ** before buying, otherwise you will definitely lose money

It's a drop, 991 is not bad.

Others include the FX9750 Plus

fx9860g slim

fx7400g plus

classpad 330

9750gll new

7400gll new

It's all sold only if you have to find a manufacturer.

1. First take out the casio calculator and press ON to open the calculator first.

2. Here a random division is calculated, and the fraction is displayed.

3. You also need to press d<=>s to become a decimal.

4. Then start to modify the settings, first press shift, as shown below, and then press the "mode" key.

5. After a bunch of selections appear, press the number "2" button.

6. Then, the setting is completed, and then calculate a division casually, and press = directly to appear decimals.

<> this is standard notation.

Press eng at this point

can be converted into scientific notation.

Press ENG again to convert back to standard notation.

Extended Materials. 1、 ms mr mc m- m+

The calculator has a memory in it, which is empty by default (i.e. 0). It can hold any value, or only one value. You can think of it as a box that can only hold one thing.

1) ms: Save the current displayed value.

2) mr: Read the numerical value in the memory and display it.

3) mc: Clear the saved data.

4) m-: Subtract the currently displayed value from the saved value, and then save the result.

5) M+: Add the current displayed value to the saved value, and then save the result.

2、rcl sto

RCL is the view variable, and STO is the assignment.

3、deg rad grad

1) d(deg) r(rad) g(grad) represent the angle system, the radian system, and the percent system, respectively.

2) The computer has four states: norm, fix, eng, sci, and the functions are: specifying the index mark range, decimal point setting, engineering calculation, and significant digit setting. If the calculator is in the other three states, an arithmetic error may occur.

4. deg is the state in which the angle of the calculator is set to degrees, and there are six kinds of it:

1) deg—Specify degrees as the preset unit.

2) rad—Specify radians as the preset unit.

3) gra—Specify the gradient as the preset unit. Also known as "percent" and "newness".

4) °—Specify the degree as the unit of a certain input value.

5) r—specify the unit of radian as an input value.

6) g—Specify the unit of gradient as an input value.

5、hyp sin cos tan ln log

1) sin cos tan is a trigonometric function, and sin-1 cos-1 tan-1 corresponds to an inverse trigonometric function, which is equivalent to arcsin, arccos, and arctan.

2) HYP is a hyperbolic function of sin, cos, and tan.

3) ln is the natural logarithm ln a=loge a.

4) log logarithmic function.
