If you need homework help, go someplace that cares. try yahoo answers. everyone seems to be asking for homework help there.

You should get 0 in this case...

PS: Wolfram Alpha says you're correct, it does equal zero.

PPS: if you're working in radians, 2 pi is a full circle, so that x any whole number is the same as sin(0), which is zero.

Don't punch a British kid, the queen'll come after you.

Is your calculator set to work in radians not degrees?

Congratulations. You're literate!

sin(2*pi*f*t) = 0 for any whole numbers f and t.

My bad, I do get 0. But I don't see why. I'll make a graph though.
Draw a unit circle. You can see that Sin(2pi) = 0. Go around another 2pi. You get sin(4pi) = 0. So long as you have (2pi)(k) in the interior of the sin where k is a whole number, it will equal zero.

The graph doesn't fit with the equation. When I do the math, it comes out different from where the y value is relative to the x value.
That's because you have an equation in 3 variables. If you're trying to figure out what happens when you change one of the values, you have to set two of the variables constant.
