Best ResponseYou've already chosen the best response.1suppose you have a vector that is 12 feet in length, how do you find out its "unit" length?

Best ResponseYou've already chosen the best response.0that's all that's given :\

Best ResponseYou've already chosen the best response.1yeah, and to find the length of a vector, you square the parts, add em up, and sqrt it all ....

Best ResponseYou've already chosen the best response.1\[vector:<a,b,c,d,...,k>\]\[distance=\sqrt{a^2+b^2+c^2+d^2+...+k^2}\]

Best ResponseYou've already chosen the best response.1parts: square 3: 9 0: 0 7:49 4:16 2: 4  sum: 78 ; so length must be sqrt(78) or did i do something wrong?

Best ResponseYou've already chosen the best response.0I did that and got sqrt 79, yes?

Best ResponseYou've already chosen the best response.1vector = sqrt(78) units to find a vector of 1 unit, we divide both sides by sqrt(78) vector/ sqrt(78) = sqrt(78)/sqrt(78) units vector/ sqrt(78) = 1 unit therefore, a unit vector is created by dividing the components of the vector by its length

Best ResponseYou've already chosen the best response.0sorry my computer like died so I'm on my friends lol so it's 6/sqrt78 @amistre64 then you times that into each unit thingy

Best ResponseYou've already chosen the best response.1each component then gets divided by the vectors length to obtain components of the unit vector. 3/sqrt(78) 0/sqrt(78)  7/sqrt(78)  4/sqrt(78) 2/sqrt(78)

Best ResponseYou've already chosen the best response.1another way to notate it is just to scale the original vector by 1/length \[\frac{1}{\sqrt{78}}[3,0,7,4,2]\]

Best ResponseYou've already chosen the best response.0oh okay my problem was accepting the fact that my calculator wouldn't put my answers in fractions so I thought I must be wrong hahaha. Thanks!!
