SineCosine(圖1)-速報App

Do you need to learn how to determine the angles and lengths of a non-right-angled triangle? Need to understand how to apply the Sine and Cosine rules in this case? Need to know how to calculate the other sides and angles when you know one angle and two sides or two angles and one side or even no angles and all three sides? If the answer is Yes to any of these questions then this App is for you. The Sine/Cosine Calculator not only calculates the answers for you but it also tells you how it did it so you can understand how and when to apply the rules for non-right angle triangles.
