图形计算器

A graphic calculator can perform calculations on various graphics.

It does not have the functions of an ordinary calculator.

If you want to find the area of a graphic but don't know the formula,

or don't know what trigonometric functions are but want to find the length of the hypotenuse,

and it's too troublesome to substitute values into the formula deliberately,

this calculator is very convenient in these situations.

By inputting the sides and height of a graphic, you can obtain the area and volume. For example:

If it is a triangle, you can find the area and perimeter through the sides and height;

If it is a cuboid, you can find the volume and surface area through two sides and height;

If it is a sphere, you can find the volume and surface area through the radius.

The graphics that can be calculated will be recorded after this article. Some formulas are also recorded in the application.


The angle units that can be used in the application are "degrees", "radians", and "degrees, minutes, and seconds".


[Usage Method]

After selecting the graphic you want to calculate and inputting the values, various calculation results will be displayed.

For example, when you want to find the area of a rhombus, select "Quadrilaterals, Polygons".

Then, after selecting the rhombus among them, a value input screen will appear.

Since it is a rhombus, input the lengths of the two diagonals and then press the calculation button.

The area, perimeter, and the values of each angle will be displayed in the output section at the bottom of the screen.

As shown above, after selecting the graphic to be calculated and inputting the values, results such as the area will be displayed.

On the calculation screen, to let the user know which type of graphic is being calculated, a schematic diagram of the object will be displayed first.

After clicking the red pen in the lower right corner of the input panel, you can edit the current values.

[Precautions]

・The author does not assume any responsibility for any damages caused by using this application and any claims from third parties.

・Since the units will change according to the object of calculation, they are not recorded. Please convert the units according to the object of calculation.

・Even if the input values form an impossible graphic, as long as they can be substituted into the formula, the calculation will be performed.

・In the calculation of angles, due to processing reasons, there may be errors in the conversion between degrees, radians, and degrees, minutes, and seconds.

・The number of significant digits is 15.

・Although we have conducted tests, if a problem occurs, please send us a problem report.

・If this application receives favorable reviews, we will continue to add the functions that everyone hopes for.

The graphics that can be calculated are as follows.

(The supported angle units are "degrees", "radians", and "degrees, minutes, and seconds")
