In the project on page 344 we expressed the power needed by a bird during its flapping mode

where A and B are constants specific to a species of bird, v is the velocity of the bird, m is the mass of the bird, and x is the fraction of the flying time spent in flapping mode. Calculate ∂P/∂v, ∂P/∂x, and ∂P/∂m and interpret them. as
