Interactive Unit Circle. Sine, Cosine and Tangent ... in a Circle or on a Graph. 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.
Formula for the Unit Circle. The formula for the unit circle relates the coordinates of any point on the unit circle to sine and cosine. According to the formula, the x coordinate of a point on the unit circle is cos(θ) c o s (θ) and the y coordinate of a point on the unit circle is sin(θ) s i n (θ) where Θ represents the measure of an ...
