OpenStudy (galleara):

Looking for help on number 3

OpenStudy (anonymous):

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

OpenStudy (galleara):

ok, can you explain more?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (galleara):

oh ok sorry I suck at word problems so bad haha

OpenStudy (anonymous):

do you get what i mean that they will cancel?

OpenStudy (galleara):

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

OpenStudy (anonymous):

exactly!

OpenStudy (anonymous):

sin(2pi) = 0 also

OpenStudy (galleara):

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

OpenStudy (anonymous):

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

OpenStudy (galleara):

thanks :) i really hate these big problems haha

OpenStudy (anonymous):

is that for a physics class?

OpenStudy (galleara):

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

OpenStudy (anonymous):

yes, it can get overwhelming sometimes haha

OpenStudy (galleara):

lol well thank you again :)

OpenStudy (anonymous):

you're welcome!
