Answer 1

Here is your problem:
\[\LARGE x^2+xy-y^2=4\]

Answer 2

x^2 + xy - y^2 = 4
2x + y' - 2yy' = 0
?

Answer 3

Correct so far, finish it

Answer 4

yay.
y'(1-2y) = -2x
y' = -2x/(1-2y)
?

Answer 5

how is xy y'?

Answer 6

x' = 1
y'=y'
1(y')=y'

Answer 7

I thought product rule meant xy = u'v + uv' = y + xy'

Answer 8

This isn't product rule though :P

Answer 9

so luigi am i rite?

Answer 10

Wait.. is it?

Answer 11

well you differentiate each term by itself. it could be o.o

Answer 13

wolfram says it's y

Answer 14

According to my work from a year ago.. I used product rule too..

Answer 15

easy problem

Answer 16

x^2 + xy - y^2 = 4
2x + y + xy' - 2yy' = 0
ok.
y'(x-2y) = -2x-y
y' = (-2x-y)/(x-2y)

Answer 17

Yes you have to use product rule

Answer 18

for xy

Answer 19

I got the second one shamil got using the product rule
