Question 66

The D'Alembert solution of the wave equation $u_{xx}=\dfrac{1}{c^2}u_{tt}$ with $u(x,0)=f(x)$ and $u_t(x,0)=g(x)$ is:

$u(x,t)=\dfrac{f(x+ct)+f(x-ct)}{2}+\dfrac{1}{2c}\int_{x-ct}^{x+ct}g(s)\,ds$✔️
$u(x,t)=f(x+ct)+f(x-ct)$
$u(x,t)=\dfrac{f(x+ct)-f(x-ct)}{2}+\dfrac{1}{c}\int_0^x g(s)\,ds$
$u(x,t)=f(x)g(t)$

Correct Answer Logic:

D'Alembert's formula gives the general solution of the 1D wave equation: $u(x,t)=\dfrac{f(x+ct)+f(x-ct)}{2}+\dfrac{1}{2c}\int_{x-ct}^{x+ct}g(s)\,ds$. It represents two travelling waves moving in opposite directions.

English QUESTION #4440

Question 67

To become a write think of a plot-make points on how the story will progress and pen it down. The phrase ‘pen it down’ here means:

To writ
To write✔️
To throw the pen
To throw it down

Correct Answer Logic:

The phrase "pen it down" means **to write** because in this context, "pen" is used as a verb meaning "to write or compose," and "down" suggests putting thoughts onto paper. The passage ends with the instruction: *"Think of a plot—make points on how the story will progress and pen it down,"* which clearly encourages the reader to write the plot points on paper. The other options—"to writ" (an archaic or incorrect form), "to throw the pen," or "to throw it down"—do not fit the logical or grammatical meaning of the sentence.
