Basic and rich Trigonometry concepts part 2, proof of compound angle functions

thumb_basic and rich trigonometry concepts part 2 compound angle relations proofs top

Trigonometry first established relationships between the angle and side measurements of a right angled triangle by defining trigonometric functions and thus extended the reach of mathematics wonderfully. Like any other branch of mathematics, from the basic trigonometric function definitions more advanced function relations are built stage by stage. Here we will deal with compound angle trigonometric function relations in more details...
