By "unit circle", I mean a certain conceptual framework for many important trig facts and properties, NOT a big circle drawn on a sheet of paper that has angles labeled with degree measures 30, 45, 60, 90, 120, 150, etc. (and or with the corresponding radian measures), along with the exact values for the sine and cosine of these angles.
2 I just recently did a project on the unit circle and the three main trig functions (sine, cosine, tangent) for my geometry class, and in it I was asked to provide an explanation for why sine is the y coordinate and cosine is the x coordinate.
In mathematics, the unit circle is a circle with a radius of one. Frequently, especially in trigonometry and geometry, the unit circle is the circle of radius one centered at the origin (0,0) in the Cartesian coordinate system in the Euclidean plane. The unit circle is often denoted S1; the generalization to higher dimensions is the unit sphere.
Since the circumference of the unit circle happens to be $ (2\pi)$, and since (in Analytical Geometry or Trigonometry) this translates to $ (360^\circ)$, students new to Calculus are taught about radians, which is a very confusing and ambiguous term.

Maybe a quite easy question. Why is S1 S 1 the unit circle and S2 S 2 is the unit sphere? Also why is S1 ×S1 S 1 × S 1 a torus? It does not seem that they have anything in common, do they?
The only thing that is changed is x x, now if we assign coordinates to real (cos x (cos x) as x x coordinate and complex value (sin x) (sin x) as y y coordinate (or imaginary axis), then this is same as parametric equation of unit circle with x x as parameter. As x x increases, the path traced by the point will be circular.
Above is a diagram of a unit circle. While I understand why the cosine and sine are in the positions they are in the unit circle, I am struggling to understand why the cotangent, tangent, cosecant,...
The unit circle only has measure 0 0 as a subset of C C. But you're looking only at functions defined on the unit circle, so it becomes the base set of your measure space, and as such can have measure ≥ 0 ≥ 0. Regarding 1 2πiz 1 2 π i z how can the density of a probability distribution be complex? You'd have to define what that means ...
The cosine and sine functions are defined on the unit circle. The reason for this is that when working with similar triangles you often want to figure out their relative scaling and the easiest number to multiply by is 1 1.
