DROP
CREATE
UPDATE
ALTER
UPDATE is a Data Manipulation Language (DML) command used to modify data in existing rows of a table. On the other hand, DROP, CREATE, and ALTER are Data Definition Language (DDL) commands, which are used to define and modify the structure of a database.
Differentiate between 'w' and 'a' file modes in Python.

Ms. Veda created a table named Sports in a MySQL database, containing columns Game_id, P_Age, and G_name.
After creating the table, she realized that the attribute Category has to be added.
Help her to write a command to add the Category column.
Thereafter, write the command to insert the following record in the table: Game_id: G42 P\_Age: Above 18 G_name: Chess Category: Senior
A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
