Answer

Answer:

To sketch the solution curves: (a) For the initial - condition (y(-2)=1): Start at the point ((-2,1)) on the direction - field. Follow the direction of the arrows in the direction - field to draw the curve. (b) For the initial - condition (y(3)=0): Start at the point ((3,0)) on the direction - field. Follow the direction of the arrows in the direction - field to draw the curve. (c) For the initial - condition (y(0)=2): Start at the point ((0,2)) on the direction - field. Follow the direction of the arrows in the direction - field to draw the curve. (d) For the initial - condition (y(0)=0): Start at the point ((0,0)) on the direction - field. Follow the direction of the arrows in the direction - field to draw the curve. There is no single numerical answer as the task is to sketch curves.

Explanation:

Step1: Understand the differential equation

The given differential equation is (\frac{dy}{dx}=x^{2}-y^{2}). The slope of the tangent line to the solution curve at any point ((x,y)) is given by (x^{2}-y^{2}).

Step2: Use initial - conditions

Each initial - condition ((x_0,y_0)) gives a starting point for the solution curve. For example, for (y(-2) = 1), the starting point is ((-2,1)).

Step3: Follow the direction - field

The direction - field shows the slope of the solution curves at various points in the (xy) - plane. Starting from the initial - condition points, we follow the direction of the arrows in the direction - field to sketch the approximate solution curves.
