I am struggling to solve this question ..
I know how to solve non-homogenous 2nd ODE if we have cos, sin and exponents .. but for in this question, we have a constant term.
I replaced the constant term by k for the particular solution .. is it wrong ?
Please see attached working.
A second order differential equation is given by 3.7(d2x/dt2t +3dx/dt+2x)=0.8, with initial condition x(0)=-1 and dx/dt(0)=-2. Solve the ODE and hence compute x(2.9). Give the answer to 3 decimal places.
Correct answer is -0.114
How do I get that answer ? what am I doing wrong ?
