Math Ref

Great reference.

Useful for grade school math through linear algebra / integral calculus. Great interface too. Love this app!

It's just an organized collection of formulas. If you keep encountering hard to understand mathematical concepts explained in impenetrably arcane mathematical jibber-jabber, look elsewhere. This app is for those who already have a deep understanding of mathematics.<br/><br/>Just once, I'd like to see an app writer come up with one that lets the rest of us on board by explaining concepts in plain language, using analogies, animations or whatever else it takes to help the rest of us break through.

A friend of mine recommended me to get this app, and my was this worth the investment! The developers deftly managed to condense the most essential of maths and physics into one convenient app. But, granted, I think the app needs a name change, in order for this app to not appear limiting. Before I bought this app, I thought there were only math related notes and such, but there physics things, financial doodads, pleasant surprises like the prime numbers and so much more. <br/><br/>There are also other tidbits worth mentioning, like having a quadratic solver, a triangle solver, etc. That said, I'd like some things to be added, or at least tweaked, like e.g. In the quadratic solver, the answer are given in decimals; it'd be great if you added an option to express them in their full notation, as in 1/2 +sqrt(3)/2i. In the triangle solver, I'd recommend an option to express angles in minutes and seconds as well.<br/><br/>Just in case, check for some spelling or context errors, because I remember I spotted one in the financial section. One last thing I want to point out is what I disliked when you guys overhauled the app for iOS 7 was that everything was 'expanded out', in the sense of that the sections were like in this opened state displaying their content. It would be less of a hassle to list the sections, and make us tap them to reveal their contents, for the sake of organizing.

As a software engineer, I find myself using this app often as a quick reference for questions in statistics, calculus, and physics when I'm working on a variety of problems. I've been using it for about 4 years, and haven't looked back. In fact it gets better and better with updates. Always the first app I install on my iPhone.

This app is great! It's very well organized and easy to use.

I've only owned this app 15 minutes and already I am very impressed. I can tell that in my role as a modeling analyst I will call upon this application frequently! Well done!

It’s a nice reference source for those who already know a subject. If you have a background in, say, trigonometry, and you know that a certain formula exists but can’t quite remember what it looks like, then this is a useful reference. <br/><br/> I don’t think it is meant to be a learning tool. If you have no idea about trigonometry, for example, this won’t do you much good. <br/><br/>This runs on a tablet but is really meant only for a phone. On my iPad everything is confined to the left-hand one-third of the screen leaving the rest of the screen blank. Maybe not a problem for most people, but I use my tablet more than my phone so that is kind of disappointing.
