Perform the indicated operations for the resulting complex numbers if the given changes are made in the indicated examples of this section.

In Example 2, change the sign of the angle in the second complex number and then divide.

Data from Example 2

Divide the first complex number of Example 1 by the second. Using the r(cosθ + j sinθ) notation, we have

divide 3.61(cos 56.3 + jsin 56.3) 1.41(cos 315.0 + jsin 315.0) subtract 3.61 [cos(56.3-315.0) + jsin(56.3-315.0%)] 1.41 = = 2.56[cos(-258.7) + jsin(-258.7)] 2.56(cos101.3 + jsin101.3) =
