Question

CAn U find the derivative for this equation PLZ TT^TT

Answer 1

\[\sin (xy)+^{2} = x -y\]

Answer 2

oh no -.-

Answer 3

\[\sin (xy) + x^{2} = x - y\]

Answer 4

oh boy..... I'm sorry, but I didnt do very well in Geometry... :-/

Answer 5

:] weeee xD

everybody is smart except me

Answer 6

thats calculas -.-

Answer 7

O_O

Answer 8

who can solve this TT___TT

Answer 9

i tell you what i got

Answer 10

and i know its wrong

Answer 11

\[y \prime(xy+y) = -\cos (xy)y-2x\]

Answer 12

it wrong i know -..-

Answer 13

please do not underestimate yourself!! we are all people just like you :)

Answer 14

please !!!

i thought u were going to type the answer

Answer 15

=_=

Answer 16

i am doing on paper 1 sec :)

Answer 17

:B

Answer 18

do you want to solve for y' ?

Answer 19

yup

Answer 20

ok lets do it together take first term

Answer 21

first you will get \[\cos xy \]
apply chain rule and use product rule for xy

Answer 22

that will be?

Answer 23

\[y \prime =\frac{ -\cos (xy)y -2x }{ (xy+y) }\] ?

Answer 24

there is a mistake ..lets do afresh that will help you more :)

Answer 25

so answer my qn above did you differentiate first term ?

Answer 26

tell me what you get?

Answer 27

cos (xy) (y+x y prime ) ??

Answer 28

yep :)

\[\cos (xy)(xy'+y) \]

who told you are dump ?

Answer 29

now next term :)

Answer 30

\[\dfrac{dy}{dx} x^2=?\]

Answer 31

cos(xy)(xy′+y)+2x = -y′

Answer 32

good but there is a small mistake :) check again ?

Answer 33

i see no mistake sir -.-

Answer 34

oh right ;B

Answer 35

cos(xy)(xy′+y)+2x = 1 -y′

Answer 36

:) now i feel like i am dump :P

Answer 37

xD ..

its okie i think i got it now

Answer 38

thanks

Answer 39

:) good ..a medal for your intelligence XD

Answer 40

:P

Answer 41

thanks and bye ..

;) talk to u later igtg complete studying :B

Answer 42

ok best of luck :)
