Maths problems, SIN, COS, TAN ???!?!! HELP!!!!

HafizulKMS SG

I work for a company as a business software developer, and then this smart boss throws me into another project. He said this is a BIG PROJECT! But I have a problem, because this is a project for game development!! I dont have any background on this kind of project, blah blah blah...

Now, I have to learn SIN, COS, TAN, and etc. May I know where can I get those references? I think some secondary references may have those topics right? I cant remember any of those things, because I left my school for more than 10 years!

Anyone can help by suggesting some references where I can get from popular bookstore? May I know it's sec 3/4/5/6 topics?

I just need some simple reference materials.

Millions thanks for the helps. I am so stress up!

SIN COS TAN?

Learn the base rules use TAO CAH SOH

Tan = Adjacent/ Opposite
Cos = Adj / Hypo
Sin = Opp/ Hypo

simple

also learn the 3-4-5 rule to get a right angle

sq 3 = 9
sq 4 = 16
sum = 9 + 16 = 25

sqrt 25 = 5

hence 3-4-5

Thanks for the reply and constructive suggestion.

I will go to find some sec4 A maths books today in popular bookstore. Sorry I can't buy second books because I don't have time to meet and etc.

Wa... I tell you, Maths is VERY important!!

You see, even building a bloody game, you need lots of mathematics. When a monster cast one spell, the spell has to travel axis XYZ by following some rules, thus all this COS, SIN, and TAN come to play. Can't even simply let the spell just shoot like that.

Really headache. Game development is really no fun.
