Question

determine whether the following ordinary differential equations are (a) nonlinear (B) linear time-varying or (c) linear time-invariant

dy/dt +(e^2t)y=0 ?

Answer 1

Use integrating factor method to solve this function.
Integrating factor is \[u(t)=e^{\int\limits_{}^{}e ^{2t}dt}\]
Next, solve this function to find the value of y given by:
\[y=\frac{ c }{ u(t) }\]; where c is a constant.
Then try to determine whether ur answer is linear or not.
