^^ ^^ 1.) Given the two vectors b=x+y and c=x+z find b+c, 5b+2c 2.) r+s = (r1+s1, r2+s2, r3+s3), if r and s are vectors with components, r=(r1,r2,r3) and s=(s1,s2,s3) 3.) Is this correct for b+c? b+c= (bx+cx,by,cz) To me that doesn't look right, but I think I'm applying the rules correctly. I don't know how to approach 5b+2c because I don't know now to apply the scalars 5 and 2 to the vector components. How is that subquestion approached? thanks alot Edit: the ^ signs are supposed to appear over the x+y and the x+z within the b and c vectors.
