This calculator allows you to easily calculate calculations even if you do not understand trigonometric functions.
You can calculate right triangles and scalene triangles.
You can calculate memory, answer memory, π, repetition, parenthesis calculations, trigonometric functions, and the law of cosines.
You can calculate diagonal pipe cuts.

Instructions for use

Calculator section
Past calculation results can be displayed by long-pressing the "ANS" button.
Tap the calculation result label (immediately after pressing =) to mark the value on the ANS list.
You can enter the value displayed on the label by tapping the white button.
By swiping the screen left or right, the right triangle will rotate.
Swipe up or down on the screen to flip the right triangle.
Please enter 2 locations for right triangles and 3 locations for scalene triangles.
Tap "Cal" to display the calculation result.
The ``Cl'' button clears the displayed value.
You can also erase only the specified location by displaying "0" on the label.
The numerical value of the calculation result can be displayed on the label by touching the button and sliding down, and can be used for the next calculation.
Trigonometric function calculations
You can "go back" and "forward" by sliding the buttons [4] and [6].
Erase numbers by pressing the CLR button once
Press twice to reset rotation
Long press to clear numbers, reset rotation, and clear memory
It will be
Automatically input pipe outline
Example 50A -> Enter "5" "0" "1 slide"
1¼B -> Enter "1" "4" "1" "2 slides"
If you slide each twice in a row, the number will be halved.

Development section
The input method is the same as the calculator section.
Basically, input is required for all buttons, but depending on the location, it is possible to input "0".
Please enter the division of the circumference in multiples of 4.
The figure of the calculation result is an image, so it may differ from the actual shape.
