sohcahtoa is all you have to remember till you get to all those damn rules.. my mid courses next week involve trig, hope i can remember it.

Rules?!?!:confuse: What rules?!?!
Oh boy Im screwed!!!
someone correct me if im wrong
sine rule (sides?) = sin A / a = sin B / b = sin C / c
sine rule (angles?) = A / sin a = B / sin b = C / sin c (i think)
cosine rule (sides) - c² = a² + b² - 2AB cos C
cant remember cosine for angles, better study.

math is a walkover, but in the uk so are most things
I'm not to sure on the cosine rule there Goki, but the others seem fine...
I myself, hate surds. I like everything else though.
My fave is algebra, but I tend to leav all my workings dissorganised...

I have always been really good at math. It is my favorite subject. I also like history.

Make sure you remember your radain/degree conversions....
pi = 180
pi/2 = 90
pi/3 = 60
pi/6 = 30
2pi = 360
etc...
And what is especially helpful is remembering "All-Star Trig Class", marking from +x,+y as A, and moving counter-clockwise marking each quadrant A S T C.... in the A quadrant, all trig functions are positive, in the S quadrant, Sine is positive, in the T quadrant, Tangent is positive, and in the C quadrant, Cosine is positive.
And secant ( SEC ) is the opposite of the cosine ( COS ), cosecant ( CSC ) is the opposite of the sine ( SIN ), and cotangent ( COT ) is the opposite of tangent ( TAN ).
