Question

(ylnx-xy) differentiate with respect to x

Answer 1

y / x - y

Answer 2

show him how you got it

Answer 3

the point of asking help is to show them the way of "solving" it , and explaining it, not just giving the answers.

Answer 4

Sure...
ylnx --> ln x differentiated is 1/x so
ylnx --> y /x
xy --> treat y as a constant
xy --> y
y / x - y

Answer 5

If I did that, I would be stuck on one person for quite a while.

Answer 6

aren't you forgetting something?

Answer 7

What?

Answer 8

that's why it's called "openstudy"? what's the point with throwing the answer if he/she didn't get it?

Answer 9

well he said with respect to x, so won't d/dx (x) = xx'?

Answer 10

Are you trying to get back at me for being better than you?
I mean, I did destroy you on other posts, but you don't have to be mad...

Answer 11

hi can one of you help me please!

Answer 12

Type your question out toriann.

Answer 13

lol no, the guy on the previous problem said that he didn't get it and u just yelled and threw the answer and left, that's why I'm concerned.

Answer 14

You're not concerned at all. Just trying to get back at me.

Answer 15

sstarica i got to ask a question coz i dont understand

Answer 16

Type your question out there below "Mathematics" on the left side, btw.

Answer 17

sup mariha, I'll try to help :)

Answer 18

ok sstarica

Answer 19

i typed my question on like the wall.

Answer 20

no supervisor, don't take it negatively, read what nel said, he said that he didn't get it, go check urself

Answer 21

what's your question mariha? ^_^

Answer 22

d/dx(y log(x)-x y)
| Differentiate the sum term by term and factor out constants:
= | y (d/dx(log(x)))-y (d/dx(x))
| The derivative of x is 1:
= | y (d/dx(log(x)))-1 y
| The derivative of log(x) is 1/x:
= | 1/x y-y

Answer 23

Consider the differential equation dy/dx=(y-1)^2cos(pi*x)
A) There is a horizontal line with the equation y=c that satisfies this differential equation. Find the value of C.
B) Find the particular solution y=f(x) to the differential equation with the initial condition of f(1)=0.

Im not sure how to solve these or how the questions differ.
