About ArcCalc
With two values all remaining details of an arc can be calculated. Currently supports 21 combinations of: Angle, Radius, Arc Length, Chord Length, Tangent Length, Middle Ordinate, Segment Area and Sector Area. The only combinations that cannot be calculated have an infinite amount of solutions.
Just fill in any two boxes and then click calculate or done.
Instructions can be found on the main screen by clicking the "?".
Formulae and information about arcs can be found by clicking the "i".
Be aware that some solutions can have two possible answers, for example using the Radius and Chord length theoretically can give an answer of between 0° and 180° and mirror result between 180° and 360°. In a situation like this it will only display the arc between 0° and 180°. The chord can be entered as a negative to get the arc greater than 180°.
Please let me know if you have any display or other issues. I will try to fix it as soon as possible.
Make sure to check the results before using, the developer will not be held liable for any mistakes made by using this application.

What's Changed
v1.4
- Added Gradians
- Added functionality with Radians, can now be input or output as fractions and/or in terms of pi. Check the settings.
- Fixed display issue with overflowing text (Please let me know if there are any other).
- Fixed crash that occurred on older versions of android when accessing the settings menu (Thanks to the user who submitted the crash report).
The new radian features were just finished, take care using them and let me know if anything unexpected happens, thanks.

This app needs landscape mode. I made a small spreadsheet that does this exact function. Compared it and they work alike. I added Degree Of Curve and Fillet to mine, tho.

Excellent. App crashes when chord length is 0.50 and middle ordinate is 0.25. Will await a fix.

Thanks. Your application makes me easy calculate the versine in my railway project. Try to combine with Hallade method versine. Great

Mistake found: for Radius = 900mm and chord length = 300 mm , Answer for arc length by app = 301.4 mm, Answer by manual and Auto CAD= 305.8mm. kindly go through it and please correct.
