Engineering Homework Help

I’m working on a aerospace engineering multi-part question and need an explanation and answer to help me learn.

Review chapter 1.5 of Fundamental of Aerodynamics by John D. Anderson.

Review thin airfoil theory and answer the following questions:

Question 1: If the zero-lift angle of attack of GA(W)-1 airfoil is ?=?=-4.2 deg, what are the lift coefficients at ?=?=4 and 10 deg? 

Question 2: If the moment coefficient around the aerodynamic center of the airfoil is -0.09 at zero angle of attack, what is the moment coefficient at ?=?=10 deg? 

Question 3: Calculate the moment coefficient around the leading edge for zero angle of attack.
