Notes solve triangles using trigonometry
Trigonometry is also useful for general triangles, not just right-angled ones . It helps us in Solving Triangles. "Solving" means finding missing sides and angles. We can also find missing side lengths. The general rule is: When we know any 3 of the sides or angles we can find the other 3 (except for the three angles … See more The triangle of most interest is the right-angled triangle. The right angle is shown by the little box in the corner: Another angle is often labeled θ, and the three sides are then called: … See more The main functions in trigonometry are Sine, Cosine and Tangent They are simply one side of a right-angled triangle divided by another. For any … See more What you just played with is the Unit Circle. It is a circle with a radius of 1 with its center at 0. Because the radius is 1, we can directly measure sine, cosine and tangent. Here we see the sine function being made by the … See more Play with this for a while (move the mouse around) and get familiar with values of sine, cosine and tangent for different angles, such as 0°, 30°, 45°, 60° and 90°.
