And finally we can simply add these together by superposition

to find the Laplace transform of the combined function.

Therefore the Laplace transform combined is equal to that, which I can read,

it's a little more tidily in that form therefore

we see that the answer is A.

Now finally to conclude this topic of mathematics

I'll mention that there are a number of topics that I didn't cover.

Because I think they're of lesser importance in the effie exam.

Although of course they should be covered in a more comprehensive class.

And in particular, we didn't talk about putting linear equations into matrix form

and solving by Cramer's rule.

We didn't look at a number of topics involving numerical analysis particularly

difference equations, numerical methods, numerical integration.

And solving ordinary differential equations by numerical solutions.

And finally, we didn't cover Centroids and Moments of Inertia.

Although I put this in parenthesis, because those will be covered later on in
