- Find dm/dt and d^2m/dt^2 for the following function at x = 3.
Use del x = 0.5. Compare the results against the analytic solution and estimate the percentage error.
Solution :-
m(t)=10e^(0.1t)
dm/dt = 10*0.1e^(0.1t) = e^(0.1t)
at t = 3,
dm/dt = e^(0.1*3)=e^(0.3)
Next step,
d^2m/dt^2 = (0.1)e^(0.1t)
at t = 3,
d^2m/dt^2 = (0.1)e^(0.1*3) = 0.1e^(0.3)
Next we have to estimate the error,
So
error = Analytical change in solution / Final solution
So error = [e^0.3 - (0.1)e^(0.3)]/(0.1)e^(0.3)
= 9%
