Reflection #10

I was gone most of last week so I don't think we really learned anything new so I'll talk about something I hate even tho i do understand it pretty well. This thing of which I speak of in calculus terms is called finding the " implicit derivatives. " This is a pretty simple concept to understand. The only difference between implicit and a regular derivative is that in an implicit derivative, every time you take the derivative of something with a " y " in it you have to put a " dy / dx " behind it. After you do that you then solve for dy / dx and wah lah, you have taken an implicit derivative.

Ex. Find the implicit derivative of 2x^2 + 2y = 6

-take the derivative of the function and add the dy / dx:

4x + 2 dy/dx = 0

-solve for dy / dx:

2 dy/dx = -4x
dy/dx = -2x

See, it is that simple!!!!
