Question:

Given a trapezoidal swept-back wing, the wingtip chord length b1, the wing root chord length b0, the taper ratio η = b0/b1, and the spanwise length l, try to derive the calculation formulas of area, aspect ratio, the tangent of middle line sweep angle, and mean aerodynamic chord length of the wing from the geometric relationship.
