Hi Vicky!

The important topics in Vector algebra are:

• Position vector of a point,
• Scalar component of a vector,
• Relation between direction ratios,
• Direction cosines and magnitude,
• Parallelogram law of vector,
• Unit vector,
• Multiplication of a vector by a constant,
• Scalar product,
• Cross product and
• Coplanar vectors

Hope this helps.

All the best!
