it looks too long to solve the ode by the link given above. there must be another way to solve the question.

comment Given the differential equation $\frac{dy}{dt}+a(t)y=f(t)$ , show that every solution tends to 0 as t approaches infinity.
Could you please how you applied Grönwall's inequality.

comment Need help for a beginner to floating-point arithmetic
@hardmath as you found it, machine epsilon is 0.25. so does this imply that $m_3=0$. Then,all the possible values the mantissa can take:0.110,0.100,0.010,0000?
