I have been informed that on March 7th from 6:00am to 6:00pm Central Time Lamar University will be doing some maintenance to replace a faulty UPS component and to do this they will be completely powering down their data center.
Unfortunately, this means that the site will be down during this time. I apologize for any inconvenience this might cause.

Section 3.10 : Implicit Differentiation
4. Find \(y'\) by implicit differentiation for \(2{y^3} + 4{x^2} - y = {x^6}\).
Show All Steps Hide All Steps
First, we just need to take the derivative of everything with respect to \(x\) and we’ll need to recall that \(y\) is really \(y\left( x \right)\) and so we’ll need to use the Chain Rule when taking the derivative of terms involving \(y\).
Differentiating with respect to \(x\) gives,
\[6{y^2}\,y' + 8x - y' = 6{x^5}\] Show Step 2Finally, all we need to do is solve this for \(y'\).
\[\left( {6{y^2}\, - 1} \right)y' = 6{x^5} - 8x\hspace{0.5in} \Rightarrow \hspace{0.5in}\require{bbox} \bbox[2pt,border:1px solid black]{{y' = \frac{{6{x^5} - 8x}}{{6{y^2}\, - 1}}}}\]
