Question

Find the unit vector that has the same direction as the vector v.

v=6i-8j

Answer 1

divide by the length of the vector

Answer 2

which is \[|+i-8j|=\sqrt{6^3+8^2}\]

Answer 3

Why is it 6 to the third power?

Answer 4

because i made a typo
it is
\[\sqrt{6^2+8^2}=10\]

Answer 5

divide by 10 and get
\[.6i-.8j\]

Answer 6

Got it! thank you!

Answer 7

Write the vector v in terms of i and j whose magnitude and direction angle are given.

lvl=6/7, theta =118degrees

The answer I got is 0.24i+0.75j is that right?

Answer 8

*-0.24
