Ezy Trigonometry

It's a great app, like I said I wish I had it sooner. While I already understand trig and do well in it these days, I was curious when I saw the app so I downloaded it and will now be keeping it. I was disappointed about 1 thing though, because I feel like anyone teaching trig should know this. And this is on you Mr./Mrs. Developer, you need to rationalize the denominator when you represent values in fractions. While tan pi/6 = 1/root3 may be correct in that it's the exact value, it is not simplified to the point where it would be correct on an exam. The correct way to represent this value is root3/3. This is done, for those who want to learn, so that you get the square root out of the denominator which makes it easier you to do more complex calculations down the road. It is a habit that should be drilled into your education in trig. I noticed the issue with tan, cot, sec, and csc for exact values on the unit circle. All of them have a denominator that isn't rationalized at some point on the unit circle. Until this is fixed I will keep my review at 4 stars because while it's a great app, but it does have this error that wouldn't fly for a trig professor looking for simplified exact values. Rationalizing square roots from the denominator is a simple process but it shouldn't be skipped for its simplicity by any means.

I've tried using this to help me with my homework, and I like the app because of its information; but it's lacking in its ability to find missing sides or reducing to simplistic form. It's frustrating! And I can't navigate through the app, it just shoved me in like someone walked over and handed me a protractor and said 'Here, this will help' and I don't know how it's supposed to help! Maybe expand the app a bit more and I'll redownload this.

I can't believe trig is hard. It's just presented in cryptic terms. 95% is trying to figure out the terminology. I'm sure this app would be great for someone who understands trig already. What was the authors purpose for the app? If it's teaching trig, it fails; if it's to make graphic demonstration in coded terms he should get 5. It's fun to move the arrow for a minute, that's about it for me.

First of all I can’t even open that app at all. It doesn’t even deserve a star. I tried using it on WiFi or just my data maybe that was causing it. Nope didn’t work either way. I tried shutting my phone off completely then turning it back on and that didn’t work either. Idk if it’s just my phone but don’t download it.

The circle display is great but the app crashes whenever I try to view the formulas iPAd iOS 10
