Chapter 1.1, Problem 2E

Explain the key points of Theroem 9.3.6

Use the two methods "real number solution space basis" and "complex solution space basis" respectively to solve y''+ 4y' + 4y = 0, y(-1) = 2, y'(-1) = 1

Show how to use "Change of Variables Formula for Integrals" to solve "Separable Differential Equations"

A helicopter pilot needs to travel to a regional airport 25 miles away. She flies at an actual heading of N16.26°E with an airspeed of 110 ​mph, and there is a wind blowing directly east at 20 mph. ​(a) Determine the compass heading that the pilot needs to reach her destination. ​(b) How long will it take her to reach her​ destination?
