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. Jun 9, 2023 · In a unit circle, any line that starts at the center of the circle and ends at its perimeter will have a length of 1. So, the longest side of this triangle will have a length of 1. The longest side of a right triangle is also known as the "hypotenuse." The point where the hypotenuse touches the perimeter of the circle is at √3/2, 1/2. This Math-ku activity (similar to a Sudoku puzzle) is an effective way to help your students master evaluating the sine, cosine, tangent, cotangent, cosecant, and secant functions of angles on the unit circle (note: angles are given in both degrees and radians).
