why do you make u=y'/Ry and why you take R=-1
please tell me.
and i think, you have made an error process.
because you found an equation y''+yt^4=0
but i found y''+yt^2=0. and then i used second order linear differential equation thecniques.
After that i found y=C1e^it+C2e^(-it)...

how to find general solution of this question
du/dt=u^2+t^2
please say me
i work hard but i do nat know this form of riccati equation. i know when special solution is...
