Use the Chain Rule to evaluate the partial derivative at the point (r, 0) = (2√2, 4) 1 where g(x, y) = , x = r sin 0, y = r cos 0. 2x+8y²2 8g = |(r,0)=(2√²,7) | 3 100

Part c? I'm stuck, I'm just trying to learn problems like these to help me study

What is an example of something going on in your mind or body that is automatically controlled by math or has a math equation that goes with it?

Cell phones have become a necessity for many people throughout the world because modern society has a need for constant access to the internet and the information contained within it.
