WebFeb 9, 2015 · A trick that lets you determine the coefficients very easily is to take the inner product of both sides with v j : x, v j = ∑ i = 1 N c i v i, v j = ∑ i = 1 N c i v i, v j = c j. (Notice that in the last step, all but one of the terms vanishes, which is awesome.) So we have discovered that. c j = x, v j .
