chk out any engineering math textbook or search for it on google ...there are plenty of online tutorial for laplace's transformations and their applications
as far as the textbooks are concerned you can check out advanced engineering mathematics by erwin kreyszig

Can you be clearer with your query?hey !is there anyone who can help me.i'm getting confused about the laplace transforms for RC circuit.wether the term denoting the voltage of a charged capacitor has a -ve or +ve sign if it is on the left of the =n.remember the capacitor is being discharged through a resistor.
Well I am going to assume you are talking about the following RC circuit arrangement from your question: see here. If my assumptions are wrong please upload a circuit diagram and I will help you with that diagram.dave !rose here.got my id expired so logged in as rosie.i was asking about laplace for RC circuit.consider a charged capacitor is being discharged through a resister and the voltage across capacitor being Vc with a source voltage of Vo. can i write it as follows.
Vr +Vc =Vo
where Vr the drop across resistor.
or should i write as
Vr - Vc = Vo
definitely the source and the capacitor voltage will have opposite polarities.
I(s)*R +I(s)[1/cs - 1/c* di/dt(0+) ] = V/s
is it write.
