You can put this solution on YOUR website!

Actually, it is written in any textbook on Trigonometry and in every textbook in Algebra,
which has a chapter on Trigonometry, so I really do not understand, why the tutors at this forum should replace these sources.


But, if you do not have an appropriate textbook at your desk, then there is VERY NICE introduction to trigonometry under this link

So, read from this source and have fan (!)


Do not forget to post your deepest "THANKS" to me for pointing you this source.
