Even if you don't understand trigonometric functions, you can easily calculate with this calculator.
It can calculate right triangles and unequal triangles.
It can calculate memory, answer memory, pi, repetition, parentheses, trigonometric functions, and cosine theorem.
Develop cones (including misalignment), diagonal cuts, R-cuts, T-pipes, shrimp tubes, rounded corners, rounded corners (eccentricity), hopper eccentricity, pipes from mirror plates, connecting pipes to tapered pipes, screw wings, and calculate PCD.
It is possible to display the development on the floor in full size with AR for a specific development.

Calculator section
Press and hold the "ANS" button to display past calculation results.
Tap the label of the calculation result (right after pressing =) to mark the value in the ANS list.

Automatic input of pipe outline
Example 50A -> Input "5", "0", "1 slide".
1¼B -> Input "1", "4", "1" and "2 slides".
Each slide twice in succession will reduce the value by half.
Expansion section
The input method is the same as in the calculator section.
To expand a pipe, PCD, or mirror, slide the screen to the left or right to select the expansion diagram.
Basically, all buttons need to be entered, but in some places "0" can be used.
For round corners (eccentricity), double-tap the screen after entering the numerical value for round corners to switch to the input screen.
Please enter the division of the circumference in multiples of 4.
