Do you know vectors and calculating them buggers?

(3s-5) * (8,s-2)=0

Here is some music while you ponder.

 

[Coriolis]

(3s-5) * (8,s-2)=0

If you are taking the scalar ("dot") product, this is:

(x1, y1) â‹… (x2, y2) = (x1*x2)+(y1*y2)

But I am not sure what your ordered pairs are here. Do you mean

(3,s-5) * (8,s-2)=0?

Quote from the book.

find s with calculations so that (3s,-5) stands directly (90deg i guess) on to(8,s-2)

sorry if the first was incorrect set up.

Yeah, the dot product should get you the answer you're looking for. Have you tried it yet?
