No need for Laplace Transforms, this is first order linear, so you can use the integrating factor method...
The integrating factor is , so multiplying through by the integrating factor gives
I am new to Laplace transforms and have started from the beginning with learning it.
I am troubled by the process of solving differential equations.
I have the problem:
dx/dt -4x = 8
I have rearranged to get sx - 2 - 4x = 8/s
now not really sure where to go from here. Can someone please show me?
Prove It, he's meant to do it by applying LT according his(er) professor.
i've found many threads here when people say "integrate by using trig. substitution," then i appear and say "no need for trig. sub." but then one realises that they are learning how to use a new technique on solving a problem.
yeah I'm going into year 2 Electrical engineering in october and I will be studying this in one of my modules along with fourier series and matrix algebra. At the moment I'm just looking at the material trying to see what Im up against as Im not the most mathematical person.
This question was asked by the same person using a different screen name here: http://www.mathhelpforum.com/math-he...ms-153657.html
Interesting that the same responses have been given ....
