Plot a slopefield for over a rectangle illustrating the general characterisics of the ODE. Then plot one solution to the ODE within this rectangle.

- Change only the following in
`init.m``ftx = '2*t*x';`(``'' indicates multiplication)

`initax = [1,4,-2,0];``init`in the command window to initialize the variables (or copy-and-paste in the Emporium). - See the example for
`slopef`, page , to investigate the window size`initax = [1,4,-2,0];`then make the change to`initax = [-2,2,-2,2];`in`init.m`. Save then type`init`in the command window to initialize the variables (or copy-and-paste in the Emporium). - Type
`sol1`. Answer ``y'' to draw new slopefield

- Have MATLAB draw a solution close to
by clicking near that initial condition on the slopefield.

From the graphics display we observe the actual -value. (In this case .)
