Find the general solution of the given differential equation using variation of parameters.
+ 4y = sec2t, - <1 <
4
O y = c1 + c2cos2t + c3 sin2t + 0.1251ln|sec2t + tan2r| – 0.25tcos2t + 0.125sin2fln(cos2f)
O y = c1 + c2cos2t + c3 sin2t + c4ln|sec2t + tan2t| – cztcos2t + c6 sin2tln(cos2t)
O y = 1 + cos2t + sin2t + c¡ In|sec2t + tan2t| – c2tcos2t + c3 sin2tln(cos2t)
O y = c1 + c2cos2t + c3 sin2t + 0.125ln|sec2t + tan2t| – 0.25t + 0.125ln(cos2f)
