Please help!! I am very confused and do not know how to solve this.
Provide an example of two complex numbers in the form c + di and , where c, d, e, and f are positive real numbers such that their product lies in the other possible quadrant. Support your example by determining its product.
Thank you! 😊
(c+d*i)*(e+f*i)=ce-df+i*(cf+de)
since c,d,e,f are positive real number, their product always in first or second qudrant
To have their product in seond qudrant, ce-df must ;ess than 0, that is ce>df
pick c=1,e=2,d=3,f=4, problem solved
(1+3i)(2+4i)=-10+10i,which is in the second qudrant of the complex plane.
