# Description

This App will test your knowledge on Trigonometric Unit Circle values. Students can quiz themselves to help prepare for tests and quizzes. Learning the exact unit circle values is vital to being successful in Trigonometry and some applications of Calculus.

Trig Quizzer even keeps track of your best times and high scores so you can challenge yourself and show off to your friends. At the end of each game you are provided a summary of each question, your answer, and the correct answer so you can review your missed questions.

Play from 3 different modes to test your knowledge on trig functions, inverse functions, and important identities.

From the Settings option, change the difficulty (include angles greater than 2pi and less than 0, and all 6 trig functions) and change the number of questions in each game.

You must install this app before submitting a review.

Google Play reviews now use Google+ so it's easier to see opinions from people you care about. New reviews will be publicly linked to your Google+ profile. Your name on previous reviews now appears as "A Google User".

Awesome app I love this app it has helped me so much with memorizing trig identities and formulas and the unit circle

Karâñ Båräd

Useful ... It will be more useful; if they provide value chart. After all it is a good mathe puzzle-game.

A Google User

Helpful Be great if there were a hint button. Maybe include a shot of the unit circle.

Matthew Patterson

Great app This app is very helpful if you need to memorize trig identities and special angles

User reviews

Helpful Be great if there were a hint button. Maybe include a shot of the unit circle.

Nice. Performance is good. Simple but do more than 10 in the round. I would like the whole unit circle in one round.

В наше время почти каждый имеет хоть какой-то фотоаппарат, будь то камера в смартфоне или кропнутая зеркалка, маленькая цифровая мыльница или полно кадровый аппарат. Но далеко не каждый понимает как сделать красивую фотографию; почему изображение размытое; почему слишком темное или наоборот, - пересвеченное.

В данном приложении рассказывается об искусстве и технике фотографии: набор фото поз, уроки по настройке фотоаппарата, полезные ресурсы в интернете, фотографии для наглядного примера. Вы сможете сделать собственную фотостудию, разберетесь со светотехникой и правилами фотосъемки, кроме того, у вас будет под рукой справочник маркировки объективов, и фотоаппаратов, словарь профессиональных терминов и обозначений.

Да - если вы не хотите учится, а просто "подсмотреть" новых идей для фотографий - есть и фото позы, нужно только смотреть и снимать.

Программа, особенно первых выпусков будет содержать не всю информацию описанную выше, но это лишь вопрос времени. Если у вас появится вопрос или предложение вы сможете отправить мне письмо и я постараюсь вам ответить.

Keeps track of all your purchases so you can keep track of where and how much you are spending each month. Store the information for your cards in case they are lost or stolen. Export all your purchases to view in a spreadsheet or include with your monthly expenses.

## eduFlash Flashcards

eduFlash is an app designed for students to assist them in learning key terms and definitions for their school courses. What distinguishes eduFlash from other flash card apps and memorization tools is that the terms and definitions are specific to their courses. Using our web based interface, teachers are able to quickly create "decks" of terms for their students to learn. Students can then download the decks and get practice using flash cards, multiple choice, or free response quizzes. Students can get practice on one deck or select as many at a time as they would like. When getting practice using multiple choice or free response, students get a summary of how well they did at the end.

This app must be used in conjunction with the web based application, so if your teacher is not currently using our service, let them know about it, it is free for teachers!

Teachers, to try out the app with a demo school, enter 0 for the zip code and selecting "Testing School". To get started with creating an account and creating decks go to http://www.eduflash.org
