Thank you sir !

I have one new problem

Laplace transforms of triangular wave of period 2a given by
f(t)=t (0<t<a)
=2a-t (a<t<2a)

I got the answer:
(1 / 1-e^-2as) {(2ae^-as / s) - (2e^-as / s^2) - (4ae^-2as / s) + (e^-2as / s^2) + (1 / s^2)}

But I want the answer: (1 / s^2)tanh(as/2)

Need its solution step wise.

Do you know the hyperbolic tangent?
