complex numbers problem....need help

Hi all
Could anyone out there please help me with the solution to this problem.

Express 2.91e to the power of 1+j2 in Cartesian form (x+jy)

Sorry writing it out, but I don't know how to set it out on the computer.


I have tried solving the 1+j2 first then adding this to the real number then working it out in polar form then converting it to Cartesian, but I don't know if this is right.

Any help would be much appreciated.
Thank you

You should start by separating the two parts of the complex exponential:

[tex]2.91 e^{1+j2} = 2.91{e^1} {e^{j2}} [/tex]

and then use Euler's formula on the [tex] {e^{j2}} [/tex] part.... Does that help?
