WebThe Sine Function has this beautiful up-down curve (which repeats every 2 π radians, or 360°). It starts at 0 , heads up to 1 by π /2 radians (90°) and then heads down to −1 . Plot of Cosine WebSine, 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 …
WebSine Formula. As per sine law, a / Sin A= b/ Sin B= c / Sin C. Where a,b and c are the sides of a triangle and A, B and C are the respective angles. Also, we can write: a: b: c = Sin A: Sin B: Sin C. Solved Example. Find … WebExpert Answer.
