Pure Mathematics - vectors common mistakes

Common mistakes

• Vectors in two and three dimensions common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: J1 Use vectors in two dimensions and in three dimensions..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Vectors in two and three dimensions.

• Vector magnitude and direction common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: J2 Calculate the magnitude and direction of a vector and convert between component form and magnitude/direction form..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Vector magnitude and direction.

• Vector operations common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: J3 Add vectors diagrammatically and perform the algebraic operations of vector addition and multiplication by scalars, and understand their geometrical interpretations..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Vector operations.

• Position vectors common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: J4 Understand and use position vectors; calculate the distance between two points represented by position vectors..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Position vectors.

• Vector problem solving common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: J5 Use vectors to solve problems in pure mathematics and in context, including forces and kinematics..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Vector problem solving.
