For direction in the last question it must be taken from the horizontal to the resultant, so shouldn't 10,603 degrees have been taken as a positive when adding it with 40 degrees to find the sum. Just a bit stuck on that.
We use components method when dealing with perpendicular vectors (north easterly, directly north etc) cosine when there are specific angles gives where the vectors form a triangle is this correct?
Hi Is there any other method for 2.1??? I used cosine method and got the answer wrong so I'm just wondering if the method you used is the only method to apply
Thank you for this. Never understood how to workout the angle on Question 8.2. Please keep making these videos.
You welcome tune in for more
Thank you for explaining while doing the equation
More light tune in for more

We can use both on any condition

Will try to work it out
