In Problems 29 and 30, a = 〈2, 8〉 and b = 〈3, 4〉. Find a unit vector in the same direction as the given vector. 2a − 3b
Added by Magdalena C.
Step 1
Given \( a = \langle 2, 8 \rangle \), we find: \[ 2a = 2 \cdot \langle 2, 8 \rangle = \langle 2 \cdot 2, 2 \cdot 8 \rangle = \langle 4, 16 \rangle \] Show more…
