3. Trigonometry: Trigonometry is the study of angles and triangles, relying heavily on three basic functions: sine, cosine and tangent, and their inverses, Cotangent (Cot), Secant (sec) and Cosecant (csc). These functions are abbreviated as "sin", "cos" and "tan". [100%] 2023-02-17 [Mathematics] [Trigonometry]...

6. Trigonometry: Trigonometry (from Greek Τριγωνομετρία "tri = three" + "gon = angle" + "metr[y] = to measure") is a branch of mathematics that deals with triangles, particularly those plane triangles in which one angle has 90 degrees (right triangles). Trigonometry deals with relationships between the sides ... [100%] 2023-02-04
