Interactive Trigonometry Calculator at Mac App Store analyse

Voila, très simple dutilisation, des resultats qui ne sont pas arrondis au centieme (ce qui est plutot pratique parfois). Personellement je lutilise très regulierement au travail.

Der erste Eindruck war sehr gut, als Ich dann aber als Erstes von einem gleichschenkeligen Dreieck und einem bekannten Winkel dazwischen die dritte Seite berechnen wollte, stand ich erst mal auf dem Schlauch: ich bekam nur Fehlermeldungen bis ich drauf kam, dass es nur berechnet, wenn ich einen gegenüberliegenden Winkel eintrage, statt dem Winkel zwischen den bekannten Seiten. Dazu musste ich aber erst wissen, dass meine fehlenden Winkel gleich sind und die Summe der drei 180 beträgt. Das Nachsehen müssen wollte ich mir aber genau mit dem Kauf der App sparen. (For the Developer: you are missing a Module for Triangels with two equal sides - using the existing Module Oblique Triangels you are forcing the User to enter the opposite angle - even when entering the opposite angle you are returning an Input error, although the calculation is correct. Try angle-a: 64, side-a: 72, side-b: 72)

This app just made half an hour of adv math homework into about 5 minutes

I would however like to see the area of calculated triangles included for convenience.

The screen shot you see with the seven diagrams are literally the only types of equations done - the author, who gives no trail to reach him - states that this is the only calculator youll need - every equation! Nonsense. What I needed, implied by the three circle diagrams (well two of them), was only one function Id love to have: the ability to solve calculations between a chord, a radius, the arc, and the height between the chord and the arc. I need this for figuring seating in a radius countertop situation. This calculator gave me absolutely nothing to do that. It didnt claim it did that specifically, but the claims made here were so grossly exaggerated that I thought just maybe Id get lucky, given there is no way to contact the developer. So - if you dont see your function on the screen shots above, then DONT GET THIS! I gave this program 2 stars because it does a few things well. And denied it the remaining because the developer implies beyond its capabilities. If he gives a way to reach him and I am satisfied that he can work with people purchasing this app then I will redo my evaluation. Thanks!

Not bad, but the basic right triangle does not use the normal conventions for labeling sides and angles. (angle A or alpha opposite side a. Angle B or beta opposite side b. etc. The author has them reversed, and no way to give him (or her) feedback.
