Consider the three vectors
The point
- Show that
lies on the line passing through and . (1 mark)
--- 2 WORK AREA LINES (style=lined) ---
- The point
is the point such that . - Show that
lies on the line passing through and , and lies between and . (2 marks)
--- 5 WORK AREA LINES (style=lined) ---
- The complex numbers
and are all different and all have modulus 1. - Using part (ii), or otherwise, show that
is never a cube root of . (2 marks)
--- 5 WORK AREA LINES (style=lined) ---
