+118667 divide 9(cos5pi/4+i sin5pi/4)/3(cos pi+i sin pi)
\(9(cos5pi/4+i sin5pi/4)/3(cos pi+i sin pi)\\ =\frac{9e^{(5\pi/4)i}}{3e^{(\pi/4)i}}\\ =\frac{3e^{(5\pi/4)i}}{e^{(\pi/4)i}}\\ =3e^{(5\pi/4)i-(\pi/4)i}\\ =3e^{(4\pi/4)i}\\ =3e^{\pi i}\\ =3(cos\pi+i sin\pi)\\ =3(-1+0)\\ =-3\)
+2 This is amazing site with amazing people! People here are very generouse and can solve any math problems without call-downs unlike other forums. I have two favorite websites helping me with my homework, humanities at cheap essay writing service and exact sciences at web2.0calc forum.You are awesome, guys!
