I found 3, 5 and 7 respectively for the components x1,x2 and x3. but I have a doubt about these values,
I had to Find the components of d=(3,5,7) along the directions of u, v and w
consider: u=1/3(2,2,-1) v=1/3(2,-1,2) w=1/3(-1,2,2), finally I got 3,5,7. this is really confusing me:confused:
Oh...thank you very much ehild, I really appreciate your help:smile:, I have another problem, can you explain me little bit about mutually perpendicular unit vectors:smile:
hello! please someone help me,:smile: here is my question.
Find the components of d=(3,5,7) along the directions of u, v and w
consider: u=1/3(2,2,-1) v=1/3(2,-1,2) w=1/3(-1,2,2)
I don't know where to start, I need some ideas to solve this
thanx:smile:
Hello guys I've asked to prove following equation on determinants, here it is;
Using the properties of determinants & without expanding prove that,
