10-23.

Use Euler's method with a step size of to estimate

*, where*

*and*

*. Use the second derivative to determine whether this is an under or over estimate.*

Since , this is equivalent to

*.*

Therefore

*.*

Starting at , so the next point is

Starting at , so the next point is

Now repeat this process three more times.
