Solving right triangle in trigonometry is really easy. We just need to remember some mnemonics and a little background in Pythagorean Theorem. This topic is very powerful in many ways. Right triangle has a...

In the previous topic we discussed about the method of getting the sum of finite sine series. Now we will extend our learning to cosines. In this topic I will give a three simple...

In trigonometry, it is easy to find the sum of finite series of sine of angles using our heroic calculator. What about if we are ask to find an expression to represent such series?...
