Perform the indicated operations. Express results in polar form. See Example 3. 7085 115.62 4667 296.34

Question:

Perform the indicated operations. Express results in polar form. See Example 3.

7085∠115.62° − 4667∠296.34°

Data from Example 3

Perform the addition 1.563∠37.56° + 3.827∠146.23°. In order to do this addition, we must change each number to rectangular form:

Converting back to polar form, we get 3.641∠122.24° (see Fig. 12.17).
