Vectors drawn the origin O to the points...

Vectors drawn the origin `O` to the points `A , B and C` are respectively ` vec a , vec b and vec4a- vec3bdot` find ` vec A C and vec B Cdot`

Text Solution

Verified by Experts

We have, `OA=a,OB=b and OC=4a-3b`
Clearly, `AC=OC-OA=(4a-3b)-(a)`
`=3a-3b`
and `BC=OC-OB=(4a-3b)-(b)=4a-4b`
