Question:
Perform the indicated operations for the resulting complex numbers if the given changes are made in the indicated examples of this section.
In Example 4, change the exponent to 5 and then find the result.
Data from Example 4
Using DeMoivre’s theorem, find (2 + 3 j)3. Converting to polar form, 2 + 3j = 3.61∠56.3°. Therefore
Expressing θ in radians, we have θ = 56.3° = 0.983 rad. Therefore,
