As "task1.m" script runs from "P2amain.m" script, it must output the following two plots (no user

inputs required):

(i) The "stagnation streamline" plot (the shape of the semi-Rankine body: r/R) in the range of: 09⁰,

179° (upper half surface) and = 181°, 191°, 201°,... 351° (lower half surface).

19°, 29°,.

(ii) The "pressure coefficient" plot (the surface pressure distribution over the semi-Rankine body: C₂) in

the range of: 0=9°, 19°, 29°,... 179° (upper half surface) and = 181°, 191°, 201°,... 351° (lower half

surface). (Note) the C, plot in aerodynamics is "negative values in positive y coordinate direction" (rule

of thumb). This will require you to modify the y axis data direction ("flip-flop" of the y coordinate) when

you perform C, plot in MATLAB.
