Vector Problems for HSC Assessment and Exam Preparation

In this video, I will demonstrate how to answer vector problems under the complex number topic using sample exam questions under the Extension 2 Maths (4U) course. Examples include:

• Vector addition and subtraction in the context of a parallelogram

• Geometric effect of multiplying and dividing a complex number by another complex number in the modulus and argument form

• Studying the effects of anticlockwise and clockwise rotation of vectors and how to achieve the result algebraically

• General problems including various trigonometry, geometry and coordinate geometry techniques

This is relevant for Year 12 students preparing for HSC Maths Extension 2 for 2020 and onwards.
