Find the eigenvalues \( \lambda_n \) and eigenfunctions \( y_n(x) \) for the given boundary-value problem. (Give your answers in terms of \( n \), making sure that each value of \( n \) corresponds to a unique eigenvalue.)

\[
y'' + \lambda y = 0, \quad y(0) = 0, \quad y(\pi/2) = 0
\]

\[
\lambda_n = \left(2n - 1\right)^2, \quad n = 1, 2, 3, \ldots
\]

✔

\[
y_n(x) = \sin\left((2n - 1)x\right), \quad n = 1, 2, 3, \ldots 
\]

✘

The figure presents a mathematical boundary-value problem where you are tasked to identify the eigenvalues and eigenfunctions given the conditions \( y(0) = 0 \) and \( y(\pi/2) = 0 \). The correct eigenvalues and form of the corresponding eigenfunctions are provided for values of \( n \) starting from 1 upwards.
