Okay I think I see what you mean. Basically what I mean is, if it was a grenade or something equivalent?

I was wondering if anyone knew what an explosion would look like in a vacuum? Theoretically let's say if something blew up in space. I was just curious because Hollywood sometimes still makes it look like an explosion on Earth but it should not be, right?

Ahh! I think that is what I needed. If 2sin(x)cos(x)=sin(2x) then I can multiply both sides by 2 which gives 2f(t)=2sin(\betat)cos(\betat). After, just carry the 2 over so you get f(t)=(1/2)sin(2\betat). Thanks man!

Sorry about that. It should be f(t).

Homework Statement Simplify this expression: f(t) = sin(\betat)*cos(\betat) Homework Equations Identities The Attempt at a Solution I started out by doing sin(\betat)*sin(\betat+\pi/2) but I can't go anywhere from there. If I use the sin(a+b) formula it brings me back to the original...
