  1. *Differentiation Q due Friday (hand in on paper) • 2010 Q2: a & b • Sketch 2+3i on an argand diagram • Find the modulus of 2+3i • Write 2+3i in polar form • Find (2+3i)7Give your answer in rectangular form • Sketch x2+y2=16 **answers to 10Q from last lesson

  2. Finding equations of Loci • A locus is a path of points that satisfy a given condition • To find the equation, write the number in rectangular form & simplify • E.g.: Find the locus of the point representing z if [z-1]=1 • Let z=x+iy This is a circle with centre at (1,0) and radius 1

  3. Find the equation of the locus of the point representing z if • (2007 Q8)

  4. Find the equation & sketch the locus:
