General Notice
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.

You appear to be on a device with a "narrow" screen width (i.e. you are probably on a mobile phone). Due to the nature of the mathematics on this site it is best viewed in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device (you should be able to scroll/swipe to see them) and some of the menu items will be cut off due to the narrow screen width.
Section 3.12 : Higher Order Derivatives
For problems 1 – 5 determine the fourth derivative of the given function.
- \(h\left( t \right) = 3{t^7} - 6{t^4} + 8{t^3} - 12t + 18\) Solution
- \(V\left( x \right) = {x^3} - {x^2} + x - 1\) Solution
- \(\displaystyle f\left( x \right) = 4\,\sqrt[5]{{{x^3}}} - \frac{1}{{8{x^2}}} - \sqrt x \) Solution
- \(\displaystyle f\left( w \right) = 7\sin \left( \frac{w}{3} \right) + \cos \left( {1 - 2w} \right)\) Solution
- \(y = {{\bf{e}}^{ - 5z}} + 8\ln \left( {2{z^4}} \right)\) Solution
For problems 6 – 9 determine the second derivative of the given function.
- \(g\left( x \right) = \sin \left( {2{x^3} - 9x} \right)\) Solution
- \(z = \ln \left( {7 - {x^3}} \right)\) Solution
- \(\displaystyle Q\left( v \right) = \frac{2}{{{{\left( {6 + 2v - {v^2}} \right)}^4}}}\) Solution
- \(H\left( t \right) = {\cos ^2}\left( {7t} \right)\) Solution
For problems 10 & 11 determine the second derivative of the given function.
