2.81*e^(i*36.4)+4.31*e^(i*71.8)=?

 

Hallo Gast!

Eulersche Identität

eix=cos(x)+i sin(x)

 

2,81ei36,4+4,31ei71,8

Winkel in Grad °

=2,81(cos(36,4°)+isin(36,4°))+4,31(cos(71,8°)+isin(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)+isin(36,4))+4,31(cos(71,8)+isin(71,8))=0,75412,7069 i+(3,8684+1,9004 i)=3,11430,8065 i
