Description by ryo sasaki (from the App Store)
This is a calculator application created by me, a canner, focusing on the functions of a calculator necessary for field work.
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.
