Answer 1

@TuringTest I feel like you'd like this problem a lot.

Answer 2

@Hero are you up for this one?:P

Answer 3

not really a challenge if you know what they are asking
for a vector of magnitude |V| at an angle theta, the component form is\[\vec V=|V|\cos\theta\hat i+|V|\sin\theta\hat j\]so just break out the calculator and calculate each component, i and j

Answer 4

|V| For this would be..

Answer 5

20?

Answer 6

the length (magnitute) of the original vector
yes, 20

Answer 7

magnitude*

Answer 8

So 20cos(60)i+20sin(60)j?

Answer 9

if they want it measured from 0 as north, then yeah

Answer 10

10i+10sqrt(3)j?

Answer 11

Or would theta be 30? Since it does state theta=30?

Answer 12

oh I misread, 60 is 30 from north
confusing lol
they tell you straight out that theta is 30, so I think that's what you should use

Answer 13

20cos(30)+20sin(30)?

Answer 14

yeah, I believe so

Answer 15

i and j are important though

Answer 16

10sqrt(3)i+10j?

Answer 17

Strange, it just flipflopped.

Answer 18

not strange\[\cos\theta=\sin(\pi-\theta)\]that's what happened here

Answer 19

sorry\[\cos\theta=\sin(\frac\pi2-\theta)\]

Answer 20

I'll learn that after this assignment, right now i only have 30 minutes left to do a problem that only Amistre would get!:(

Answer 21

Well you might, not sure.

Answer 22

I'll post a new one.

Answer 23

worth a shot
