Let <PI = 30.0deg. Substituting <PI = 30.0deg into Eq. (3.25) gives !(<p}) = -0.03979719. Equations (3.40) to (3.42) give

u(30.0) = H~cos(40.0) +¥- cos(40.0 - 30.0)] = 0.850107 (3.43) <P2 = g( <P I) = g(30.0) = COS-I [u(30.0)] = cos-1(0.850107) = 31.776742 deg

(3.44)

g'(30.0) = 2 sin(40.0 - 30.0) = 0.131899 5JI - (0.850 I07)2

Substituting <P2 = 31.776742 into Eq. (3.25) gives !(<P2) = -0.00491050. The entire procedure is now repeated with <P2 = 31.776742 deg.
