Hi,

I have the following question:

"Find the dot product of 2 vectors if their lengths are 4 and 2/3 and the angle between them is 0.75 radians?"

I am having trouble, as most examples, the angle between them is acute - so I cannot visualize graphically how this scenario works.

Or am I over-thinking this and it is simply cos(135) x 4 x 2/3?

TIA
