Question

Write the element $straight a subscript 12$ of the matrix $straight A space equals space open square brackets straight a subscript ij close square brackets subscript 2 cross times 2 end subscript comma$ whose elements $straight a subscript ij$ are given by $aij space equals space straight e to the power of 2 ix end exponent space sin space jx.$

Solution

$Given space that space of space straight a subscript ij space equals space straight e to the power of 2 ix end exponent sin left parenthesis jx right parenthesis Substitute space straight i space equals space 1 space and space straight j space equals space 2 Thus comma space straight a subscript 12 space equals straight e to the power of 2 cross times 1 cross times straight x end exponent space sin left parenthesis 2 cross times straight x right parenthesis space equals space straight e to the power of 2 straight x end exponent sin left parenthesis 2 straight x right parenthesis$
