Help with vectors

Answer 1

Which of the following is the vertical component of a vector that has a direction angle of θ = 115° and a magnitude of 0.5? Round your answer to the nearest hundredth.

Answer 2

so to find the vertical component you would do sintheta

Answer 3

$$ \Large{ x = r \cos \theta\\
y = r \sin \theta
}
$$

Answer 4

here r = 0.5 , and theta = 115 degrees

Answer 5

Oh so .5sin115=.45

Answer 6

y=.45

Answer 7

yes for the y component

Answer 8

That made this alot easier. In my notes it says ||v|| I thought it meant vector s:
