Hello,

i'm here because i didn't found anything general on this topic, i need to know what is the expression of the laplace transform a composed function like that : \(L\left \{ f(x)\circ g(x) \right \} = L\left \{ f(g(x)) \right \} = ??\)

my complete equation to transform is : \(\\ x(t)=4\times [\ddot{a}(t)cos(a(t))-\dot{a}(t)^2sin(a(t))] + 2500 \\ y(t)=4\times [-\ddot{a}(t)sin(a(t))-\dot{a}(t)^2cos(a(t))] + \frac{3.711}{4}\times t^2 + 2700 \)

the goal is to isolate the \(a(t)\) function as a function of \(x(t)\)

Thanks for your time,

Robin Luiz
