Sketch in an argand diagram the locus of point P representing z such that |Z - (-1+2i)| = sqrt (5)
Hence find the greatest value of |z-1|
I know how to skectch but dont klnow how to find the greatest value of |z-1|
you know z = 1 point right? You can draw to the loci you sketched... All points of the loci has to be taken into consideration
Then you need to find the point that gives you the largest distance.... Then probably need to do some trigo to solve it...
this part very hard to teach online leh....
so i need to find the greatest distance from the point (1,0) to one of the point on the circular loci?
correct
ok ithink i got it. thanks
