Diff equations: about _t38
hi,
having to solve a differential equation (t^2*y'=y^2+ty+t^2) in t (time) and y, with desolve I get a message from Terminal, "Homogeneous", than something like [-i*t i*t [G_0*e^ATAN(_t38) G_0*_t38*e^ATAN(_t38)]] What's, exactly, "_t38"? Is it possible to simplify in any way? I should have y(t)=t*TAN(log(|t| + c), as substituting z=y/t and so on... Generally speaking, I that G_0 is an heritage of the Queen HP50, but perhaps it would be also nice can change it into c0 (or c_0) without use always "subst()"... Thank you in advance for info Salvo ∫aL√0mic (IT9CLU) :: HP Prime 50g 41CX 71b 42s 39s 35s 12C 15C - DM42, DM41X - WP34s Prime Soft. Lib |
