sighh, i heard the alg 2 finals are really hard. made me feel quite angry inside, since it made me remember about my 91.37% in math 1st quarter. fml. if only i got that one question right on my test.
ah well, that's the past. i wonder how ima do on my finals. i don't like studying. heh, probably no one does..
is it just me, or is English sorta hard to study for. i feel like all you need to do is remember all the stories you read, and what they're about. maybe some random vocab?
nvm, it didnt work so i took it out cuz it was messing up the whole website...
i sometimes feel like the best way i study is:
1: writing on my hand
2:typing
it really depends on when and what the subject is..
like i guess for like science and social studies, its really a good idea to outline all the stuff you learned.
but, if its math, just write down the formulas that you suck the most at and write it on your hand.
however the best thing is to actually know what the semester was about..
anyways, i gotta study for this huge important math test that's gonna determine my grade for this quarter. lets see if typing helps? lalala
variations
y varies directly as x, or y is directly proportional to x, if there exists a nonzero real number k, called the constant of variation, such that
y=kx
or
y/x=k
steps:
1: write the general relationship among the variables as an equation. use constant k
3: substitute this value of k into the equation from step 1, obtaining a specific formula.
Direct Variation as nth power
n=positive real number.
y varies directly as the nth power of x
y=kx^n
or
k=y/x^n
Inverse Variation
y varies inversely of the nth power of x
y=k/x
k=xy
Joint variation
m and n = real numbers
y varies jointly as the nth power of x and the mth power of z
y=kx^n z^m
*READ AND REPEAT UNTIL YOU FIND IT STARTS TO MAKE SENSE...
