Best ResponseYou've already chosen the best response.0if your in college you must be knowing that, its a software for solving everything :) known as MATRIX lab or matlab and your vector function could have been drawn on that easily

Best ResponseYou've already chosen the best response.0i guess phasor diagram can be plotted of the function that you have given but vector function is kinda complex :/ to draw , you gotta use software

Best ResponseYou've already chosen the best response.0got it, just use different values of t and put it in your function, you can draw vector function easily, lets say at t=30 degrees ,find value of 3 sint which is = 3 * 1/2 and value of cos t = cos 30 = sqrt 3/ 2 so you got a pair that is \[(\frac{ 3 }{ 2 }, \frac{ \sqrt 3 }{ 2 } )\] similarly find value of your function at lets say t=45 your gona get 3 sin t = 3 sin 45 = 3/ sqrt 2 and cos 45 = 1/ sqrt 2 \[(\frac{ 3 }{ \sqrt2 }, \frac{ 1 }{ \sqrt2 })\] now just plot it on graph paper ;)

Best ResponseYou've already chosen the best response.0yeah i think i understand how to plot them, but since they are a vector function, isnt it supposed to be a vector? or do i plot them and then thats the vector? and i attend IUS lol nice to meet you!

Best ResponseYou've already chosen the best response.0dw:1358912629689:dw the line that i have shown by arrow is the only line just find out values at t= pi/4, pi/2 and pi finally you are done ;)
