Purpose: To investigate the qualitative behavior of the solutions of initial value problems of the form
y" + ay' + by  =  0, 
y(0)  =  y_{0}, 
y'(0)  =  y_{1}. 
In particular, to determine how solutions depend on the signs and magnitudes of the coefficients a and b and on the initial conditions.
Prerequisites: The helper application tutorial and knowledge of the symbolic form of solutions of differential equations of the form
y" + ay' + by = 0.
