2.81*e^(i*36.4)+4.31*e^(i*71.8)=?
Hallo Gast!
Eulersche Identität
eix=cos(x)+i sin(x)
2,81⋅ei⋅36,4+4,31⋅ei⋅71,8
Winkel in Grad °
=2,81⋅(cos(36,4°)+i⋅sin(36,4°))+4,31⋅(cos(71,8°)+i⋅sin(71,8°))=2,262+0,5934 i+1,346+4,094 i=3,608+4,687 i
Winkel in rad
=2,81⋅(cos(36,4)+i⋅sin(36,4))+4,31⋅(cos(71,8)+i⋅sin(71,8))=0,7541−2,7069 i+(−3,8684+1,9004 i)=−3,1143−0,8065 i
