Hi
z1.z2=(4+3i)(3-2i)
=12-8i+9i-6i^2
=12+i+6
=18+i.
To graph this on an Argand Diagram think of x axis = real numbers eg. 18 and y axis =imaginary or i axis. Line starts from the origin and extends to coordinates (Re,i)=(18,1)=z3=z1.z2
hello guys. am kind of new to the polar topic and have limited resources where notes and text book is concerned.
given that and
a) express in polar form
for that i have
=
=
=
is this correct?
can someone please show me how to evaluate
and how would i sketch on same argand diagram?
