The helix of radius R, height h, and N complete turns has the parametrization \(r(t) = \left\langle R \cos\left(\frac{2\pi Nt}{h}\right), R \sin\left(\frac{2\pi Nt}{h}\right), t \right\rangle, \quad 0 \le t \le h\) Calculate the length s of a helix if R = 8, h = 19, and N = 10. (Use symbolic notation and fractions where needed.) \(s = \sqrt{25,600\pi^2 + 361}\)

Problem 2. Given: the navigation-to-body frame Euler angles: • the roll angle, $\phi$, as 7°; • the pitch angle, $\theta$, as 10°; and • the yaw angle, $\psi$, as 235°; and the navigation-to-wind frame Euler angles: • the bank angle, $\mu$, as 4°; • the flight-path angle, $\gamma$, as 2°; and • the heading angle, $\sigma$, as 195°. Determine: a) the approximate angle of attack, $\alpha$, and sideslip angle, $\beta$, using the small angle approximation; b) the exact angle of attack, $\alpha$, and sideslip angle, $\beta$; and c) comment on the difference between the two.
