Hello, everyone. This is Tom from everystepcalculus.com and everystepphysics.com. In this video,how to do the derivative of the log, natural log of some function. And you can see function on your screen. Let’s do it. Index 8 to get to my menu. And we’re already at log of x derivative. Scroll down to that. Press enter. And we’re going to differentiate it. Because that’s what we’re doing. We’re finding the derivative. And we enter our function. In this case, you have to press Alpha before you enter anything into these entry lines on my programs. I’m going to press alpha and then it’s second to get to the log function. Here’s log of our problem. And it’s X to the two-thirds. Close off the parentheses. I always show you what you’ve entered, you can change it if you want. I say it’s okay. You press number one. Here’s the formula. Here’s over after the derivative of this. U prime over U is the formula, etc. Pretty simple but to remember all these different formulas and rules in Calculus is very difficult. That’s the reason I needed to program this stuff. The answer is 2 over 3x. Pretty neat, huh? everystepcalculus.com. Go to my site and subscribe so you can see more videos that I made you. Have a good one.
