A flat circular plate has the shape of the region x² + y² ≤ 1. The plate, including the boundary where x² + y² = 1, is heated so that the 4 temperature at the point (x,y) is T(x,y) = x² + 3y² - 3x. Find the temperatures at the hottest and coldest points on the plate.

![### Problem Statement
A flat circular plate has the shape of the region \(x^2 + y^2 \leq 1\). The plate, including the boundary where \(x^2 + y^2 = 1\), is heated so that the temperature at the point (x, y) is given by:
\[ T(x,y) = x^2 + 3y^2 - \frac{4}{3} x \]
Find the temperatures at the hottest and coldest points on the plate.
### Explanation
This problem involves finding the maximum and minimum temperatures on a heated circular plate. The plate is defined by the region inside and including the boundary of the circle \(x^2 + y^2 \leq 1\).
The temperature distribution across the plate is described by the function \( T(x,y) = x^2 + 3y^2 - \frac{4}{3} x \).
To solve this problem, you will need to use methods of calculus, specifically involving finding the critical points of the temperature function and evaluating these points within the given region to determine the maximum and minimum temperatures.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc1840ebe-b0df-4fe8-9210-d8e3dcfa32cc%2F01288cdc-8f2d-473a-87b3-9c6922a10cdf%2Fhxp3ztb_processed.png&w=3840&q=75)
