Evaluate Cross Product Formula

X × Y = (x_{2}y_{3} - x_{3}y_{2})i + (x_{3}y_{1} - x_{1}y_{3})j + (x_{1}y_{2} - x_{2}y_{1})k X × Y = (-1 x -9 - 3 x 1)i + (3 x 5 - 8 x -9)j + (8 x 1 - -1 x 5)k X × Y = (9 - 3)i + (15 - -72)j + (8 - -5)k X × Y = 6i + 87j + 13k

Parallel Check:

Since X × Y <> 0: X and Y are not parallel

X × Y = 6i + 87j + 13k Since X × Y <> 0: X and Y are not parallel

What is the Answer?

X × Y = 6i + 87j + 13k Since X × Y <> 0: X and Y are not parallel
