So that's x squared plus y squared.
X squared plus Y squared equals R squared. .
That's equal to x minus f squared plus y squared.
So minus x squared plus y squared plus z squared, with respect to x.
It's got to be equal to x squared plus y squared.
It's x squared plus y squared, so you get x squared plus y squared is equal to a to the fourth.
Well, you should already see we have an x squared plus y squared.
So it's x squared plus y squared, right?
So let's take the derivative with respect to time of x squared plus y squared.
So I have this problem, x squared plus y squared minus 2x plus 4y is equal to 4.
The sum of their squares is going to be equal to x squared plus y squared.
I will define the curve in a second-- of x squared plus y squared dx plus 2xy dy-- and this might look very familiar.
It tells us right there. r squared is equal to x squared plus y squared.
So when x and y is equal to 0,x squared plus y squared is 0, you're exactly 0 away from the center, or we're at the center.
Equals R squared. Because it's always X squared plus Y squared.
This becomes x plus f, right, minus minus, squared plus y squared is equal to 2a plus the square root of x minus f squared plus y squared.
Equals R squared. Because it's always X squared plus Y squared.
If we say that f of xy-- the vector field f is equal to x squared plus y squared times i plus 2xy times j and dr-- I don't even have to look at this right now. dr, you can always write it as dx times i plus dy times j.
And so here, we get the square root of x minus f, x minus f squared, plus y squared.
If we do some pattern matching, well x squared plus y squared we know that's equal to r squared. .
The left hand side, if you were to square it just becomes x plus f squared plus y squared.
So times 10 e to the minus x squared plus y squared plus z squared.
Left hand side--is equal to 4a squared plus 4a times a square root of x minus f squared plus y squared.
The first one, they want us to convert this, x squared plus y squared is equal to 4, to polar coordinates.
And then that is equal to 4a squared plus 4a times the square root of x minus f squared plus y squared.
I'm going to define the path in a second-- of x squared plus y squared times dx plus 2xy times dy.
And that's equal to, if you square the right hand side, a squared times the square of a square root is just that expression, x squared minus 2xf plus f squared plus y squared.
So the gradient of the temperature function is equal to minus 20 e to the minus x squared plus y squared-- you probably can't read this-- plus z squared, times i minus 20y.
So a squared is equal to x squared minus 2xf plus f squared plus y squared.
And that's just minus 2z times 10 e to the minus x squared plus y squared plus z squared.
