I am confused about what area is being minimised in the nambu goto action..the one in the target space or the one in the parameter space? From Zwiebach's book I think he is trying to construct the area in target space and in the process we get derivatives with respect to parameters since each co-ordinate in the target space is now a function of the two parameters.. But reading David Tong's notes, it seems he is building the area in the worldsheet rather than in target space...because he talks about pullback of the flat minkowskian metric on the worldsheet.. (by worldsheet i think he means the parameter space?)
