this year i am taking a trig class (because it's a requirement and because it looks good on your resume). we are learning about the unit circle. the π/6, π/3, etc etc confuses me so much. when i ask for help of course whoever is helping me asks what part do you not understand. THE WHOLE DARN THING! just do the problem for me so i can figure out the next one! so with that said, if anyone would be so kind as to explain the unit circle to me in words i would understand (just pretend you're explaining it to a 10 year old, which i'm not, but chances are i wil understand what you are saying, mathematically). thank you so much. i hope this ramble also answered the above question, "why doesn't anyone like math?" i wish i did. life would be a lot easier. i'm just more of a languages person

Encyclopedias are not pure reference books, they are conveyors of information. The choice of language used and the pacing of the concepts could use some untangling. This is of course a problem with many of the maths related articles in
Knowledge, but it becomes frustrating when consistently each article viewed has the same language/style problems. One simply ends up going elsewhere to find out what a unit circle is for and how it works.

complex plane, but the definition remains the same in either setting. The three functions you mention do not define different unit circles, they are only used to express the coordinates of the points on the unit circle in different ways. If you actually found sources for your point of view, you should probably throw them away as being useless.--
262:
i don't like math because the concepts are confusing. i don't enjoy math because if you don't understand one small detail, then your entire answer is off, or you don't know where to begin in solving the problem itself. math leads to frustration in my experience. it has always been my worst subject.

Hi, I'd like to help people like me and myself in the future, who fall in this trap and confuse between UC in the complex plane, UC of sinus and UC of cosinus. I want to add a pic of 3 circles instead of the main image that will illustrate the differences. And plus I think there is a room to add the

Perhaps I did not make myself clear enough. The images you posted are wrong! You have given cartesian coordinates of some points on various curves, but in no case do these points lie on a circle (unit or otherwise). At the very least, these diagrams are misleading and would do considerable harm to

While you did initiate a discussion of this on the appropriate talk page, the lack of responses should have told you something. Your serious confusion of basic concepts made it hard for editors to react in a meaningful way. One could distinguish between unit circles in the

This article is another truly terrible maths article within
Knowledge. Maths -isn't- hard if it is explained properly. The information in this article may be technically correct but if the knowledge cannot be conveyed clearly and simply to the audience then it is failing the encyclopedia.
686:
I can't see that the new image is better than the one that was there. It's lower quality, uses confusing notation, some of which is just plain wrong. The lead image should simply have one unit circle with some appropriate decorations, not 4 with incorrect use of ordered pairs.
229:
In the representation of the triginometric functions in the unit circle, it would be useful to add that the values of the tangent of an angle theta are also represented by the vertical tangent to the unit circle and the values of the co-tangent by the horizontal tangent.
379:
This article needs to be a reference. It is deeply related to how and why the unit circle works. The first section "Forms of unit circle points" even gives the formula without linking to it or explaining what it is.
