Hello everyone.

Sorry I have not been participating much lately. I am in new courses, and I tend to envelop myself in what I am studying at that moment.

My last class introduced us to Laplace transforms, and my new class is starting off with them. I thought I had them figured out, but now I am not so sure.

I have attached my problem, my work, my wrong answer, and the book's answer below. Maybe the the book is wrong (It wouldn't be the first time). I dont know. But I'll doubt myself before the book.

If anyone knows their Laplace transforms, please take a look at my work. I would like to know where I am going wrong.

Thanks

silvrstring,

In the third line of your work, you write the Laplace transform of -2x as -2*L(x). It should be -2/(s^2) . Ratch
