Hi..new here. I'm having trouble finishing off a very basic laplace transform problem. I'd greatly appreciate it if someone could show me the way. The problem is #5 from this picture: http://www.flickr.com/photos/67208468@N08/6111476312/ What I did was use the Euler's formula for sin t and I got to this: 1/i * (-s2e-pi*s+i+e-pi*s)/s2+1 The answer is (1+e-pi*s)/s2+1 I always kinda get confused typing math/equations, so I apologize if what i described wasn't clear. Thanks for any help.
