Implicit Differentiation
Ever tried to solve for y in a complex equation like x²+y²=1? Sometimes it's impossible or too complex. That's when implicit differentiation comes to the rescue! This technique lets you find the derivative without isolating y.
The key is to remember that whenever you differentiate y with respect to x, it becomes dy/dx. When differentiating terms with y variables, use the chain rule by multiplying by dy/dx. After differentiating both sides of the equation, gather all the dy/dx terms to one side and solve.
Let's see an example: For xy + y = 8x, we differentiate both sides:
- Left side: y + x + = y +
- Right side: 8
- Solving for dy/dx: = 8-y, so dy/dx = /
Pro Tip: When finding the second derivative , first find dy/dx, then differentiate again using the quotient rule. It gets complex, but breaking it down step-by-step makes it manageable!
For second derivatives, like in x² + xy² + y³ = 27, you'll first find dy/dx, then differentiate again. Remember to substitute your expression for dy/dx into the final equation for d²y/dx².

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
