Solution

This question more related to \'deifferenciation\' in Mathematics of matlab(comp. Q)

Please find the ans.; please let me know if any quesitons related -

function dydt = order2(t,y)

dydt = zeros(size(y));
a=2.4;
b=1.44;
r=10*t*e*(-1.2*t);
dydt(1)=y(2);
dydt(2)=r-a*Y(2)-b*y(1);

===============

dydt = order2(t,y)
dydt=> (a)= 2.4+1.44*r
=> 2.4+1.44*-(a*Y92)-b*y(1)
=>3.84*-92aY-b*y(1)
substituting for y(1), dydt(size(y))
=> 3.84*-92aY-b*1
=>3.84*-92aY-b
