External Triangle

This application is a Triangle calculator[Triangle Solver]. (From some known value input, it calculates other value.)
Repeating a similar calculation is sometimes necessary. Full number input again and again is a nuisance. Don't you think it's better if the calculation result comes only by different point correction? This application fulfills it.

For educational purpose, it equips with Deg/Min/Sec, π(radian), fraction, square root in input and calculation result display.
I added many calculation combinations in comparison with other triangle calculator.
Height, area, perimeter, inscribed circle radius, circumscribed circle radius can be used as input for calculation.
And it calculates triangle from 3points, 2points and 2angles, 2points and 1side1angle.

Not all calculation finishes with getting the result. You often have the demand such as follows.
・To get results when the input is different. And the results of more various inputs.
・To get the input of the adjusted result.
This application watches a touch action to display number itself and does numerical value correction or input.
It makes simpler and easier the operation (correction, recomputation) like above cases.

(Spec)
・Triangle 3 sheets, Circle 1 sheet and 1 simple auxiliary total sheet (2 items total) is equipped.
・The touch action direct to the digit you want to change, makes numerical input or modify. It automatically calculates the results.
・3 kind Numeric keyboards are equipped. (DegMinSec/√/Fraction/π can be entered)
・Fraction/√/π can be entered and displayed.
・Copy / paste function of a sheet or each numeric.
・1 memory
・Triangle shape display
・Configurable rounding location. Classified length/area/angle.
・Configurable angle unit. DegMinSec/Degree/Radian/Gradian.
・Configurable length unit. Normal/yard-inch/feet-inch.
・Selectable decimal point/separator(5) and separator position(4), and numeric(18 or 19(iOS8)).
・Landscape mode display (iPhone/iPod touch: one numeric enlargement / iPad: split screen)
・iPhone/iPod touch: 10-digit display / iPad: 14-digit display
・Internal calculation operations: 16-digit decimal(Not binary floating/double) or fraction or square root. (For error minimising)
・Multitask (for i-Pad) and Handoff (2 units or more) of iOS are available.
