Find dy/dx for the implicit function: xy+x=e^y
Have you started the problem?
To do these you just treat 'y' as some unknown function of x...
i dont know how to differentiate e^y...
so for example, differentiating 'y' : d/dx (y) gives you y' differentiating some function of y, like say, y^2 you use the chain rule: d/dx (y^2) = 2*y*y'
ah ok so the rule for e^f(x) is (e^f(x)) ' = e^f(x) * f '(x)
so it's e^y * y'
\[(e ^{y})\prime = e ^{y} *y \prime \]
is it x(dy/dx) + y + 1 = (dy/dx)(e^y) dy/dx = -(y+1)/(x-e^y) ??
yes
thanks!
give @Algebraic! a medal please
you're welcome
rfl
how can i give a medal?? i am new here
press best response button next to one of his responses
\[xy+x=e^y\] \[\frac{\text d}{\text dx}(xy+x)=\frac{\text d}{\text dx}e^y\] \[y+x\frac{\text dy}{\text dx}+1=\frac{\text dy}{\text dx}e^y\] \[(x-e^y)\frac{\text dy}{\text dx}=-(y+1)\] \[\frac{\text dy}{\text dx}=\frac{-(y+1)}{x-e^y}\]
pretty
i wish someone did that to my replies....
what do you mean?
i meant what @EulerGroupie did. he told you to give @Algebraic! a medal...no one ever tells people to give @lgbasallote a medal...
:(
:*(
dere u go XD
lol i didn't say no one gives me medals. i said no one tells others to give me medals
