Pollination is the transfer of pollen from the male parts of a flower to the female parts of a flower of the same species, which results in fertilization of plant ovaries and the production of seeds.
Choose your x and y carefully. Scientists like to say that the independent variable goes on the x-axis (the bottom, horizontal one) and the dependent variable goes of the y-axis (the left side, vertical one).
If the functions fi are linearly dependent, then so are the columns of the Wronskian as differentiation is a linear operation, so the Wronskian vanishes. Thus, the Wronskian can be used to show that a set of differentiable functions is linearly independent on an interval by showing that it does not vanish identically.
