i just got another idea since <v,v*> just depends on v* so we just treat it as a function of v* and then we have the last step ?

actually i don't understand the last step Phi is taken out of the sum because it is linear in the 2nd variable ? And "V is the dual space of V*"looks very confusing The dual space of V is the set linear functions on V Now the dual space of V* is the set linear functions on V*? how can i see that ?

Not my homework It's in the textbook - lectures of diff geo by s.s.chern Just put them down in a clearer way Could anybody explain the questions in the pic ? http://x7d.xanga.com/be6d931344030137094065/z100635368.jpg"
