[cirthix]

its not a specific problem, just me not understand the concept

 

[chuckywang]

the concept can best be explained with solving problems. What's the question you have?

 

[cirthix]

thanks chronoshok, the links sorta helped

 

[cirthix]

useless stupid post.. anyways

i'm sorta getting it, so i'll post back when i have problems

 

[cirthix]

i'm stumped, and dont get the concept

yx^2+xy^2=6
find dy/dx

 

[chuckywang]

dy(yx^2+xy^2)/dx = dy(6)/dx

2x*y+dy/dx*x^2+y^2+x*dy/dx = 0 (using product rule twice, perhaps it would be easier if you wrote y as y(x))

solve for dy/dx
