I'm using wangsness EM book. I keep doing ch 1 #5 and keep getting 19, despite the back of the book saying -14.4
A = <2,3,-4>
B = <-6,-4,1>
AxB = <-13, -22, 10> = D
Find the component of AXB along the direction of Vector C
C = <1,-1,1>
Now I am using
C•D = CDcos(theta)
Im getting 66.4º
Now, to get the component I used:
Magnitude = DCcos(66.4)
Does this method make sense?
