Find dy/dx by implicit differentiation y^5+x^2y^3=1+x^4y I got: (-4x^3y+2xy^3)/(x^4-3x^2y^2-5y^4) Can someone show me the steps to verify the correct answer? :)
5y^4 y' + 3x^2y^2 y' + 2xy^3 = 4x^3y + x^4 y'
? Can you show the full steps.
well i am, just differentiate with respect to x.
|dw:1349985400305:dw| Hmm ok there's the first step, look ok so far? c:
yeah that makes sense.
|dw:1349985816493:dw| Ok good your answer looks the same. Your signs are different since you moved the (y')'s to the RIGHT instead of the left. So your tops are all a factor of -1 off from mine. and your bottoms are all a factor of -1 off from mine. -1/-1 = 1, so we have the same answer :) good job!
awesome thanks! Does it matter which side I move the y' too?
