I am currently having problems with few math assigments and I have no idea how to solve this one.
Determine standart T in that way, that A = (T-1)i + 2j and B = 3i + Tj
a) that they are parallel
b)perpendicular to each other
No idea how to solve this assigment eventhough it is very basic one :#
So anyone able to help me here?
