Question 1023507
.
Please Help Me With This: Show That The Vectors a=5i+3j+3k, b=3i-3j+k, c=7i+8j+5k are collinear
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


They are not collinear.


The determinant of the corresponding 3x3 matrix of coefficients is not zero.
It is -4.


The determinant of the matrix {{{(matrix(3,3, 5,3,3, 3,-3,1, 7,8,5))}}} is -4.
