Go, Scala, and Julia are fundamentally different languages designed for distinct engineering ecosystems: Go is built for cloud infrastructure, microservices, and high-concurrency networking; Scala is tailored for enterprise data pipelines (like Apache Spark) and robust backend systems; and Julia is engineered specifically for scientific computing, high-performance mathematics, and data science

A JSP file (with a .jsp file extension) stands for JavaServer Page. It is a text-based, server-side document used to create dynamic web applications by embedding Java code directly inside HTML markup

When a user requests a .jsp page, the web server passes it to a JSP Engine. The engine automatically translates the JSP code into a standard Java Servlet (a .java file), compiles it into a .class bytecode file, and runs it on the server. The server then sends pure HTML back to the user's browser, meaning the client never sees your underlying Java source code

1. A.

   The given ellipse (x²/16) + (y²/9)=1 can be represented as given below:

   

   Ellipse is symmetrical about x-axis and y-axis.
   So, area bounded by ellipse = 4 x Area of OAB

   $\begin{array}{l}Area\text{of OAB}={\displaystyle {\int }_0^{4}ydx}\\ ={\displaystyle {\int }_0^{4}3\sqrt{1-\frac{x^2}{16}}dx}\\ =\frac{3}{4}{\displaystyle {\int }_0^4\sqrt{16-x^2}dx}\\ =\frac{3}{4}{\left[\frac{x}{2}\sqrt{16-x^2}+\frac{16}{2}{\sin }^{-1}\frac{x}{4}\right]}_0^4\\ =\frac{3}{4}\left[\frac{4}{2}\sqrt{16-4^2}+\frac{16}{2}{\sin }^{-1}\frac{4}{4}\right]-\frac{3}{4}\left[\frac{0}{2}\sqrt{16-0^2}+\frac{16}{2}{\sin }^{-1}\frac{0}{4}\right]\\ =\frac{3}{4}\times 8\frac{\pi }{2}\\ =3\pi squareunits\\ Therefore,\text{area bounded by ellipse}\\ =4\times Area\text{of OAB}\\ =\text{4}\times 3\pi squareunits\\ =12\pi squareunits\end{array}$
