Looking for help on number 3

anonymous · Answer

well from what i glanced at, i would assume that if you plug in your the frequency variable into your s(t) equation, it would cancel, leaving you with just the coefficient. so it's not important to know the value of the frequency

galleara · Answer

ok, can you explain more?

anonymous · Answer

okay so you solved for your s(t) equation, right? well inside your s(t) equation you have 'w*t' (w=small omega).... w = 2*pi*f, and it's asking you to replace t in your equation with 1/(4f)... and so on. well when you multiply w*t, the f's cancel

anonymous · Answer

go ahead and try to plug the value of t into your s(t) equation and you will see that the frequency variable will cancel

galleara · Answer

oh ok sorry I suck at word problems so bad haha

anonymous · Answer

do you get what i mean that they will cancel?

galleara · Answer

i think so. so if i do sin(2*pi*f(1/f)) it's sin 2pi?

anonymous · Answer

exactly!

anonymous · Answer

sin(2pi) = 0 also

galleara · Answer

cool :) thank you for helping me understand that!!!

anonymous · Answer

you're welcome, good luck with the rest of your hw

galleara · Answer

thanks :) i really hate these big problems haha

anonymous · Answer

is that for a physics class?

galleara · Answer

nah just precalc algebra and i always look over the important stuff and forget what i'm doing

anonymous · Answer

yes, it can get overwhelming sometimes haha

galleara · Answer

lol well thank you again :)

anonymous · Answer

you're welcome!
