the eqution
d^2u/dt -k(1-u^2)du/dt+au = 0
initial condition
u(0)=2 (dimensionless); du/dt (0)=0
question
(a) With ?? = 1.0 s-1, determine the value of ?? that would give a heart rate of 1.25 beats/second and Graphically display ??(t) for this value of ?? and 0 ≤ t≤ 5 ?? . (25 points).
(b) Graphically display ??(t) for your chosen values ?? and ?? and 0 ≤ t ≤ 5 ?? . Interpret the results.
