Hi, i'm david and i'm hachianian, see your question.

Now let me bring up your question here.
00:05
In the question here, we're given the equation of the curve x square plus y square equal to the 4.
00:12
We need to find the equation of the tantal that parallel to the line x equal to the 3.
00:18
When the line x x equal to the 3, we have the slot.
00:21
On this line, it will equal to the undefined.
00:27
Now, from this equation, first of all, we need to do the d of the 3 the x.
00:33
So if we do that, the x squared derivative equal to the 2x, derivative the 2x, derivative the y squared equal to the 2 y times the d, y over the d x equal to for the constant it will equal to the 0.
00:47
From here we have the dy over the x, it will equal to the minus x over y...
