unit vector = [math]\tfrac{(3i + 7j + 4k)}{√(3² + 7² + 4²)}[/math]
unit vector = [math]\tfrac{(3i + 7j + 4k)}{√(74)}[/math]
unit vector = [math]\tfrac{3i}{√(74)}+\tfrac{7j}{√(74)}[/math]+
math]\tfrac{4k}{√(74)}[/math]
unit vector = [math]\tfrac{(3i + 7j + 4k)}{√(74)}[/math]
unit vector = [math]\tfrac{3i}{√(74)}+\tfrac{7j}{√(74)}[/math]+
math]\tfrac{4k}{√(74)}[/math]
