Question

Sinusoidal functions tie into Sin, Tan, and Cos, right?

Answer 1

sin

Answer 2

only sin? i'm just learning it lol so all these different functions are kinda confusing... ok thanks.

Answer 3

yeah, do you have any specific question though?

Answer 4

State the amplitude, period, vertical shift, phase shift, and reflection for the sinusoid y = -2 sin (2x - p/4) - 3.

i know how to find the amplitude, and there is a v.s of 3 down. the other ones i'm not sure on

Answer 5

reflection not sure but phase shift should be 1, and period is pi

Answer 6

f ( x ) = a sin ( bx – c ) + d, for b > 0.
period= 2pi/b
phase shift = c/b

I'll see if I can find something on reflection, been awhile since I've done this stuff

Answer 7

ok cool. any sites that explain in depth will help alot :) i'm more of an english than a math person... thanx!

Answer 8

never mind, phase shift is pi/8 I wasn't thinking... haven't really found anything that explains reflection to me sorry ....

Answer 9

http://dwb4.unl.edu/chem/chem869m/chem869mmats/sinusoidalfns.html this site explains the reflection, and the rest very well at the bottom of the page!

Answer 10

ooh ok thanks. this site helps alot! yay lol
