Construct `a3×2m a t r i xA=[a_(i j)]` whose elements are given by `a_(i j)=e^(i x)sinjx` `a_(i j)=e^(-i x)cos(pi/2i+j x)`

Explanation

To construct the \(3 \times 2\) matrix \(A = [a_{ij}]\) with the given elements defined by two different expressions, we will follow a systematic approach.

### Step-by-Step Solution:

1. **Define the Matrix Structure**:
The matrix \(A\) will have 3 rows and 2 columns, so we can write it as:
\[
A = \begin{bmatrix}
