Coordinate systemMatch the following equations with their direction field Clicking on each picture will give you an enlarged view While you can probably solve this problem by guessing it is useful to try to predict characteristics of the direction field and then match them to the picture Here are some handy characteristics to start with you will develop more as you practice A Set y equal to zero and look at how the derivative behaves along the z axis B Do the same for the y axis by setting equal to 0 C Consider the curve in the plane defined by setting y 0 this should correspond to the points in the picture where the slope is zero D Setting y equal to a constant other than zero gives the curve of points where the slope is that constant These are called isoclines and can be used to construct the direction field picture by hand 1 g 2 2 y 2 2y z e 2x y 3 g 2y 4 g y 2 11 11
