Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same. no matter how big or small the triangle is. Trigonometry Index Unit Circle.inside the unit disc. Let B(z) = p⋆(z)/p(z). (2.1) Then B is analytic in D, continuous on the unit circle, maps Dto itself, the unit circle to itself, and the complement of the closed disc to itself. Therefore B is a Blaschke product. Now for k ∈ N, the set of points in Dfor which B(z) = z−k lie on the unit circle. Therefore,Pi is a mathematical constant and irrational number representing the ratio of a circle’s circumference to its diameter with a value of approximately 3.1416. It is possible to calculate the area of a circle by multiplying the square of its r....
