find the desired equation.
a.) $\displaystyle y=c_1+c_2e^{3x}$
taking two derivatives
$\displaystyle \frac{dy}{dx}=3c_2e^{3x}$
$\displaystyle \frac{d^2y}{dx^2}=9c_2e^{3x}$
b.) $\displaystyle y=c_1e^{ax}\cos(bx)+c_2e^{ax}\sin(bx)$ a and b are parameters.
can you help me continue with the problems. thanks!
