Thanks Vela. If that's all i got wrong then i am quite happy!

Manged to final get to this answer: df/dx (x)+ f(x)= 3 ℓ ( df/dx+ dx) = l 3 ℓ ( df/dx )+ l (dx) = l 3 ℓ ( df/dx )= f^' (x)= sF(s)- f(0) ℓ (dx) = F(s) ∴ sF(s)- f(0) + F(s) = l 3 ∴ sF(s) – f(0) + F(s) = 3/s F(s)(s + 1) – f(0) = 3/s F(s)(s + 1) – (-2) = 3/s F(s)(s...

I have put down the whole question and my answers which i would appreciate if someone could comment: Part 1.1 Find the general solution of the equation (d^2 z)/(dx^2 ) - 4 * dz/dx + 13z = 0 Put into form: a * m^2 + b * m + c ∴ m^2 - 4m + 13 = 0 a = 1, b = -4, c = 13 Then: m_(1,2 =...

Homework Statement Solve df/dx (x)+ f(x)= 3 under the condition f(0)= -2 using the Laplace transformations Homework Equations The Attempt at a Solution Not even sure where to start on this one. Dont have any examples that point me in the right direction. Any ideas anyone??
