• #### tricks to help u memorize sum mathematical terms ajacob2013

i hope some of u will fin this useful

SIN, COS and TAN: if u dont know when or where to use these, then this will help u.

think of "CAH SOH TOA".

CAH stands for Cos=Adjacent over Hypotenuse

SOH stands for Sin=Opposite over Hypotenuse

TOA stands for Tan=Opposite over Adjacent

if u r unsure of knowing what kind of a line on a graph is positive or negative, thn this might help u: these are two lines going different directions-\ /

this line / looks like a fada in irish and is therefore positive

this line \ looks like hitler's salute and so it is negative.

i really do hope this works for u and if anyone else has more helpful tips pls share them.

thank u

I use, Sin: Oh Hell Cos: Another Hour Tan: Of Algebra. The capital letters stand for Opposite, Adjacent, Hypotenuse. It works for me

Two old angels (Tan = o/a) sitting on high (Sin=o/h) chatting about heaven (Cos = a/h)

S=O/H

C=A/H

T=O/A

CRAPPY (cos)

TRIG. (Tan)

science:

density

-think of the formula as a love heart: mass m

--------- = --

volume v

12. #### ajacob2013

mass m

------- = --

volume v

For memorising mode, median and mean:

MODE has 4 letters and so does MOST. So MODE is the number that comes up the MOST.

Median sounds like Mid so the median is the middle number

The Mean has an 'a' and Average has an 'a'. So the mean is the average number
