c^2=3/2+0.5c^2 0.5c^2=3/2 c=√3?

sorry they don't cancel. so c=√3?

so its √3+c? giving me c=(√3+c)*1*cos60 which c's will still cancel?

[1,2√,c]⋅[0,0,1]= (1)(0)+(2√)(0)+(c)(1)= c lzl=√1^2= 1 lvl= √(1^2+√2^2+c^2)= (√3)c c=(√3)c*1*cos60 Im using equations we have used in class but it doesn't seem to work with c variable on both sides

When i simplify the equation, the c is canceled out and I am left with no variable?

ok (0,0,1) would seem the simplest, but how would i use the dot product method to solve for c because when i tried using (0,0,1), and then (0,0,2) i got different answers?

thanks for the replies, I really appreciate the help. I'm still confused as to why you gave c a value of unit vector one though?
