multiply 8 with the u vector
okay so its -56 -16
yeah but put it in proper notation like <-56, -16>
oh okay ididnt kno it was that simple
Let u = <7, -3>, v = <-9, 5>. Find 4u - 3v.
im going to do this one
careful while you can multiply the same way when subtracting it's u1-v1, u2-v2 because u =
and v =
ok i didnt kno tht, thanks!
Calc III is easy what I'm dealing with is crazy XD
lol what are u dealing with?
differential equations proving something ughhh
are you in college?
yup. I'm gonna attempt something and post it on here. I figure if i solve it first like I usually do, then I might get it.
okay so far i got 4(7,3)-3(-9,5)
multiple the 4 with <7,3> - multiply 3 with <-9,5>
is it <1,3>
its not in my answer choice
huh? What are your answer choices?
oh crud my bad. I don't think you have to distribute the negative. try <1,-3>
yh i think its tht :)
it's been a ywear since I've done some, but I still remember some of it
okay what do i do for this one Let u = <-4, -3>. Find the unit vector in the direction of u, and write your answer in component form.
gotta find the formula or the format for component form. I need to finish my stuff. sorry.
ok but thank you soo much :D
