best to describe Vector
F = ƖFƖ × unit vector
has angle
None from the options
only has magnitude
2
unit vector
for F
also can be written as
3sin α j + 4cos α i
sin α j + cos α i
4sin α j + 3cos α i
This is a trick question, impossible to find the unit vector

Would be more interesting if someone else is teaching.
it's like experiencing the first sip of beer in engineering
TOTALLY WASTE OF TIME.. TOTALLY
Challenging and yet interesting

How important it is to have a strong foundation in mathematics for you guys? (Not graded)
Waste of time knowing mathematics, i am an engineer duh!
Dey! I don't see any purpose of knowing the fundamentals
Mathematics only for mathematician
Very important. it is like oxygen gas. without it we die

What
F
equal to?
3 i - 4 j
- 3 i - 4 j
3 i + 4 j
- 3 i + 4 j
8
Which of the trigonometry functions is right?
sin2 α + cos2 α = 0
sin2 α + cos2 α = 1
sin2 α = cos2 α
