Question

z=x+(x+1)i the mod of z is 5. find x

Answer 1

mod of z=a+bi=sqrt(a^2+b^2)

Answer 2

is it 3 and -4

Answer 3

nvm it is

Answer 4

\[x^2+(x+1)^2=25\]\[2x^2+2x-24=0\]\[x^2+x-12=0\]\[(x+4)(x-3)=0\]u r right

Answer 5

hm can you find the argument of Z from this ?

Answer 6

arg1=atan(4/5) and arg2=-pi+atan(3/4)

Answer 7

is that right??

Answer 8

almost i got different values for arg1

Answer 9

z=3+4i
theta=Arctan(4/3)

Answer 10

yeah oops thought 5 was 3.. wb the second arg

Answer 11
