In this lesson I explain how to find second derivatives. Here are the questions I've used 👇 1. Find d²y/dx² for y = 5x³ - 7x² + 5 2. Find d²y/dx² for y = 2 - 6/x² 3. Find f''(x) for f(x) = 5/x² - 3/2x⁵ I hope that you find the lesson useful. Subscribe to my YouTube channel to stay up to date with new uploads and follow me on Instagram @themathsprof for more maths!
