Hi,


I have the following question,

I tried the following answer 0,3,1 but it's not correct,

The question asks what is the product \(\displaystyle t_1\cdot t_2\cdot t_3~=~?\)

I'am a bit confused what is given is a [multiplication ] + [Addition] , how can I do the dot product then ? Like i know how to do simple dot products but got confused here

thanks

I think that the answer is simply \(\displaystyle 0\).
I would have to see the text material to be sure.
The questions asks for the product of the components of \(\displaystyle t~.\)

thank you 0 is correct. However it will be nice to know the steps u took to get there.

thanks

\(\displaystyle t = 2\left[ {\begin{array}{*{20}{c}}
1\\
1\\
0
\end{array}} \right] + \left[ {\begin{array}{*{20}{r}}
{ - 2}\\
1\\
1
\end{array}} \right] = \left[ {\begin{array}{*{20}{c}}
0\\
3\\
1
\end{array}} \right]\)

\(\displaystyle t_1=0,~t_2=3,~t_3=1\) and \(\displaystyle (t_1)(t_2)(t_3)=(0)(3)(1)=0\)

0 is correct. However it will be nice to know the steps u took to get there.

What steps did you take, that you ended up with something different? What did you get after multiplying the first vector by its scalar? What did you get after adding the two vectors? What did you get when you multiplied the three resulting components?

Please be complete. Thank you!

I see, i got 0,3,1 , however i didn't do the final multiplication, I guess that was what i missed.

Thank You for your help guys
