WebThe Circumference is the distance once around the circle. And here is the really cool thing: When we divide the circumference by the diameter we get 3.141592654... which is the number π ( Pi) So when the diameter is 1, the circumference is 3.141592654... We can say: Circumference = π × Diameter WebThe Unit Circle. The point of the unit circle is that it makes other parts of the mathematics easier and neater. For instance, in the unit circle, for any angle θ, the trig values for sine and cosine are clearly nothing more than sin(θ) = y and cos(θ) = x.Working from this, you can take the fact that the tangent is defined as being tan(θ) = y/x, and then substitute for …
