Question

(Differential Equations QUIZ)
What is the solution of.....

Answer 1

\[\cos (x+y) dx + \left( \cos (x+y) - 2y \delta m y ^{2} \right)dy = 0\]

is the answer
\[\sin (x+y) - \frac{ 1 }{ 2 } y \delta m\]

Answer 2

????

Answer 3

@Arhin hbu???

Answer 4

@zordoloom hbu??

Answer 5

@gerryliyana sorry, I can't be of much help. I'm studying this stuff myself.

Answer 6

yes.., of course

Answer 7

ok @zordoloom niver mind :)

Answer 8

I got the same thing but with y^4 instead of y on the right side. Let me try to check on mathematica.

Answer 9

ok..,

Answer 10

I tried, but I have no idea of how to do that on mathematica.

Answer 11

On your first formula, those are all y right? (-2 delta m y^3)?

Answer 12

sorry i was wrong,
Hopes correct after correction
my answer becomes:

\[\sin (x+y) - \frac{ 1 }{ 2 }y ^{4} \delta m\]
hbu?

Answer 13

Thats what I got.

Answer 14

ok.., thank u @ivanmlerner :)

Answer 15

Your welcome, ok now I'll go sleep

Answer 16

ok :)
