Question

Find dy/dx

Answer 1

sin(xy) =2x+5 through Implicity

Answer 2

How much do you know or are able to do?

Answer 3

@swin2013 do you plan on answering me or do you not want my help?

Answer 4

i had to attend to other businesses. cos(xy) *(y+x*dy/dx) = 2

Answer 5

Correct! So you do know! Now solve for dy/dx.

Answer 6

ok... i did it right. i thought i did it wrong lol

Answer 7

Yes you differentiated correctly but now you should express dy/dx in term s of x and y. In other words, isolate dy/dx.

Answer 8

i got 2 - cosxy *y / -x = dy/dx

Answer 9

No, if\[(y +x \frac{ dy }{ dx })\cos (xy)=2\]then\[y \cos (xy)+x \cos (xy)\frac{ dy }{ dx }=2\]
\[x \cos (xy)\frac{ dy }{ dx }=2-y \cos (xy)\]
\[\frac{ dy }{ dx }=\frac{ 2-\cos (xy) }{ x \cos (xy) }\]

Answer 10

OH you distributed. ok i gotcha
