Question

hey someone asked this question earlier,
I would like to know how to solve it
what is the exact values of y(2)
if y'=sin(xy)

Answer 1

i been stuck on it for the longest time

Answer 2

what does y = cos(xy) derive to?

Answer 3

not that its the answer

Answer 4

y' = (x'y + xy')-sin(xy) right?

Answer 5

y + x(sin(xy) = 1then maybe

Answer 6

y'=(x'y+xy')(-sin(xy))

Answer 7

lets assune it was -c0s :)

Answer 8

then y + x(sin(xy)) = 1 would be good right?

Answer 9

y = -sin(xy) x +1 ..... dunno if that helps but it might :)

Answer 10

he said: the final answer is suppose to be y(2)=1.632
lets see if that equation holds for his answer

Answer 11

do you know anything about euler's method?

Answer 12

only by name; havent rad to much into it tho

Answer 13

i don't i can do this problem right now my head hurts from trying to find y(2).
i
