you mean y' right?
y' = cosx ^_^
wait a min, it's: y' + y = sinx
if so, then y= sinx - y'
y'=(sinx-y)/(sinxcosx) ? i dont fully understand the question DX
lol no, the question is : y' + y = sinx
whats the sinxcosx?
wait....it's the derivative of sinxcosx + y = sinx
so y = sinx + sin^x + cos^2x = sinx + 1 = sinx
there's something wrong ._.
mowazzem can you please restate the question
in a more understandable way
find y' or y?
its a derivative, i need to solve this
that's mean y
you want to derive y = sinx - sinxcosx?
again, mowa is this the question you want to derive: y = sinx - sinxcosx?
no this is not a question. its a DERIVATIVE FORM sinxcosx(y')+y=sinx
and you want to find y?
then y = sinx - sinxcosxy'
as far as I have understood from the problem
wait, do you want to integrate?!
right hand side has also a derivative of y'. so your suggestion might be worng
lol! so you DO want to integrate ^_^
what class is this? calculus or diff equas?
I think it's calculus since she wants to get y
only way to get rid of y' is to integrate
oh, no wonder, diff euas (at that level) are just beyond me
just a little*
mowa, did you take integration by parts?
sstaica what do you do?
did you take integration?
do you know bernoulli equation
heard of it
general form of bernoullis equation
its semelar form of previous equation
hmm, the bernoulli that I know comes from physics P + 1/2pV^2 + pgh
are undergraduate student
you mean a college student?
yep I am, first year ^_^
or graduate student
ok, probably you don't know
are you a graduate?
its higher class math
I am doing PhD
I see, then you are right, I prolly don't know it :) still taking calculus II ^_^
whoa! GOOD LUCK :)
i know that why you usde very simple rule
lol, still learning ^^" anyways, sorry for not being able to help , I wish I could help though, you can try google? or youtube ^_^
and I wish you the best of luck :)
its very simple but I forgot. I done it about 4 yrs ago.
you can try google though , the only way I know right now is integration by parts
haha yup diff equas are some crazy fun stuff XD
mowazzem, can i ask you a question?
sorry i am going out. What you wanna ask?
