Attached below is a vector question. I'm having trouble grasping the concepts involved, but hopefully i have it figured out. Can someone that knows this stuff view the questions and perhaps verify my answers and/or steer me in the correct direction?
do you need help find component of the vector ? or unit vector?
i'll tell you where i'm at...u tell me if i'm on the right track?
a unit vector is akin to a "unit" circle, a "unit" anything = 1
"unscale the vectors by dividing out the "length"; since length/length = 1
okay...i'll just work on the A vector....i got a length of 75 and an angle of 27 degrees....so if try to find Ax i use 75cos(27) to get 66.8?
i'm not following amistre
75cos(27) is right for Ax
before this afternoon i've never seen a vecotr in my life
then for Ay i should do the samething except 75sin(27) for 34.0?
x = 27 cos(t) ; y = 27sin(t)\[\] A = <27 cos(t),27sin(t)\>[\] unitA = <cos(t),sin(t)\>[\]right?
ugh, i got lost in the nukbers; same concept tho i believe
okay...can you open the answer form attachment and tell me if that's all i put in the A vector slot?
yes, but they might want exact answer?
how would i go about exact answer?
75 cos(27) i, 75 sin(27)j
or is that my theta = artcan (ay/ax)?
let me try that again:\[\] x = 75 cos(27) ; y = 75sin(27)\[\] A = <75 cos(27),75 sin(27)>\[\] unitA = <cos(27),sin(27)>\[\]
sadly this pellet is probably easy and i'm overcomplicating it huh?
yes, you got this
it is; you want to fit the vector into the unit circle
so the x ^ that rooftop on top of the x is what part?
