Trigonometry made easy

Trigonometry, a topic you learn in maths form 3 chapter 15. Its a very interesting topic but needs memorization of the opposite, adjacent and hypotenuse. Our teachers would usually teach us this basic method of remembering which are ToaSohCah/SohCahToa. Today, ive learn an interesting way to determine the tangent/cos and sin. Its a technique which outwits, outplays and outlast all of your other measly technique. Futhermore, after hearing this technique you shall remember this until the day you die. I guarantee you on that. >.<

Instead of using adjacent, replace adjacent to side


If you think this is too obscene or you'd rather use adjacent instead of side, heres another method. I have divided it into 3:


Guys technique:

Girls technique:

or if your neither guy or girl, theres always:


Yep, thats about it. Kasturi is a great tuition centre. The teachers are superb and most of all you'll definately enjoy their lessons. With 5 more days to PMR everything has been going great. I hope the equations above has made your life easier. ^^
