App is very good, makes trig jump out at you. However, the standard mathematical abbreviations for the tangent and cotangent functions are tan and cot (not tg and ctg). Also, note that csc is an acceptable abbreviation for cosec. Also, when you select integer degrees, the animated sweep stops. Still, it's a very nice app that dynamically shows the trig function relationships.
This app is fantastic for studying trig. It really lets you visualize what each of the 6 trig functions actually mean and how the values are derived, especially tangent and cotangent. I spent an inordinate amount of my spring break playing with different angles on the unit circle and had a blast.
I found this years ago, uninstalled it after taking calculus, then was unable to find it when I needed it again. I'm glad to have finally rediscovered this valuable resource. What an awesome visual aid - great job, dev!
Please reviuw the labels and the calculations in the upper left side of the screen. Some timed you get a cos of 7 for N angle og 45 degrees. Otherwise, an excellent piece of work. An updated version would be great.
This is a really cool app that visually demonstrates what the trigonometry functions actually mean. I highly recommend it for anyone with an interest in geometry or a desire to understand trigonometry better.
Awesome. Showing my daughter trig, great visual tool. I wish I had this as a kid. It would be better if you could enter ratios to find angles.
Great app. I should recommend this to just about everybody who has even a slightest interest to understand trigonometry, and in 21st century this is much easier than few centuries b.c, when it was ALL done.
In addition to having all the math well layed out, the app is a tremendous visual representation of the numbers. Great response to my question from the developer. Excellent work. I highly recommend this app.
Enchanting! Try to make a web.app version (available for PCs) of it. Also you could make a complex planar app, where most of the complex equations could be plotted in 2D plane.
Looked at it for about 10 s, then immediately went to see if I could send the dev some money. This is a truly beautiful (and useful) presentation of the unit circle.
Great app. Clean, sharp, fast UI. Helps understand trigonometry visually. Helpful compilation of formulas.
It has potential BUT it has some errors that need to be fixed! If you are just learning trig you might be confused
I have taken a lot of math classes, but i have never seen trig presented in this kind of detail. It's great. I learned something.
Great app! Lists a lot of useful formulas, beside aiding the visualization of trig functions
three new permissions, no mention in the update notes. Otherwise a very nice app
The visualization it provides for the trig functions of sine, cosine, etc. will help your understand them better
Most useful app for my trigonometry studying! Can I download this app to my ipad pro? Do you have a plan? I want to use this wonderful app my big screen ipad pro one day! I hope!
Wonderful interactive visuals explaining the relationship between each function.
Really awesome I got helped to visualize the function easily and with many different way 😍😍🥰🤩😍😍😍🥰🤩🤩🥰😍😍 Loved it
This app is really good, i learn much about trigonometry from this rather than school. Highly recommend
This is the best app on google play! Nothing better than Trigonometry. Unit circle. 💯/💯🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🎆🎇🎆🎇🎆🎇🎆🎇🎆🎇🎆🎇🎆
Exellent!!!!!!!! All complete circle details with formula Its realy amazing !!!!!
some data is wrong for example cosec 90 - theta is sec theta and not cosec theta.
Probably the best possible unit circle you can get.
So useful and helpful app. It really deserves 5 stars.
love it perfect for watts on the moon program by nasa.
the mysteries of trigonometry become obvious on the unit circle
App Deserves 5 star but It Lag to much and sometimes doesn't respond.
Record the circle unit of some trigonometry functions.
Really great app. I don't have a great memory for remembering angles, but this app helps a ton. My only recommendation is that the back button be made to move to the previous screen. Specifically, when I click on a function value and it takes me to the projector, when I click the back button it would be nice if it returned me to the function value screen instead of leaving the app.
