(a) Quaternions offer an unconstrained method of representing attitude while Euler angles are always subject to a unit norm constraint. (b) Autorotation stall, inverted spin, and flat spin are all types of spin, which is an aggravated stall condition. (c) The Newton–Raphson Iteration method for finding the roots of a function is based on a Taylor Series Expansion about the estimated root.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
