Question

In certain physical models, the nonhomogeneous term, or forcing term, g(t) in the equation ay" + by' + cy = g(t) may not be continuous, but have a jump discontinuity. If this occurs, a reasonable solution can still be
obtained using the following procedure. Consider the following initial value problem.
240 if 0sts7T/6
y" + 4y' + 40y = g(t); y(0) = 0, y'(0) = 0, where g(t) = .
if t> 7x/6
Complete parts (a) through (c) below.
(a) Find a solution to the initial value problem for 0 sts 71/6.
The solution for 0sts 7n/6 is y(t) = - 6 e -21
*cos 6t - 2 e - 2t
sin 6t + 6
(Type an equation.)
(b) Find a general solution for t> 71/6.
The general solution for t> 7x/6 is y(t) = C, e-2 cos 6t + C, e -2t sin 6t
(Type an equation. Do not use d. D. e, E, i, or I as arbitrary constants since these letters already have defined meanings.)
(c) Now choose the constants in the general solution from part (b) so that the solution from part (a) and the solution from part (b) agree, together with their first derivatives, at t= 71/6. This gives a piecewise
continuously differentiable function that satisfies the differential equation except at t= 7x/6.
if 0st<7x/6
The solution to the differential equation is y(t) = .
if t> 7x/6

In the answer, it gives a formula f-ff=m(0) and afterwards simplies into 120 - ff = 0 and further into ff=120N. My question is how do you not have to divide by 0 to finish the equation if that makes sense. To simply further why are we able to ignore the m(0) portion?
