Homework Statement
Evaluate the following in x+iy form.
i3+i
Homework Equations
i=rei[itex]\Theta[/itex]
The Attempt at a Solution
i=rei[itex]\frac{pi}{2}[/itex]
i3+i = i3*ii
(-i)(ei2[itex]\frac{pi}{2}[/itex])
=-ie-[itex]\frac{pi}{2}[/itex]
=-.2079i
I understand how it all works out except [itex]\frac{pi}{2}[/itex]. I can't figure out how they got [itex]\frac{pi}{2}[/itex] in the first place. Any ideas? Thanks in advance.
