R. Redheffer, {\it Differential Equations}:

[6.1]: 2, 10;

[6.2]: 1, 4(b,c);

[6.5]: 4;

[8.1]: 2 (a,b);

[8.4]: 4;

By variation of parameters find a particular solution
to problem 6 (a,c,d,f,h) in [6.5].  You can stop 
as you have obtained the expressions for derivatives 
of unknown coefficients;

[10.2] 6.

All problems are estimated by 10 points, except 6 in [6.5] and 6 in [10.2] 
which are estimated by 15 points.
