tectudssr
App updated 10.10.2020
(added word wrap function)
I’ve created an Android App, shortly after A.VCE+ dead.
tectudssr cannot show pictures and can’t doing a lot of other things, but it serves me faithfully for text quizes.
Download the latest APK – v. 2.36
How to use the Application?
1. Install SumatraPDF
2. Open the pdf-test from gratisExam (didn’t tested other pdf-s) using SumatraPDF, “Save as” -> “Save as .txt”
3. Удаляю из этого текстового файла вопросы в которых нет вариантов ответа или правильного ответа (редко).
4. Rename this file to tect.txt and move it to the Download folder of tablets sd-card
Back – swipe left or Vol+
Forward – swipe right or Vol-
I’m choosing right answers (checkboxes or radiobuttons depends on answers)
now, tectudssr will show correct answers – click the bottom middle button (or swipe up):
In cases of segmentation faults, incorrect quiz parsing (and so on) leave a comment or write a mail (attach the pdf).
Android v6+ required.
Previous version: tectudssr-2.11.apk.

Решение квадратного уравнения
Квадратное уравнение – это уравнение вида ax2 + bx + c = 0
Для вычисления значения x мы сначала вычислим дискриминант по формуле D = b2 – 4ac
Если дискриминант больше нуля, то вычислим корни уравнения x1 и x2 по формулам:
ИНАЧЕ ЕСЛИ дискриминант равен нулю, единственное значение x вычислим по формуле
ИНАЧЕ ЕСЛИ дискриминант меньше нуля, то уравнение не имеет действительных корней.

При a == 0 уравнение перестает называться квадратным.
