Help with Sinisodials

[maiden canyon]

wait did u solve the first amplitude things

here

amplitude is coef so its 3

period is js 2pi/1=2pi

frequency is 1/period

which is 1/2pi

phase shift is pi/4 to the right because negative

no vertical shift cuz no constant being added or subtracted outside of function

now to grapj

js get the 5 key sin(x) points

which are

(0,0), (pi/2,1),(pi,0),(3pi/2,-1),(2pi,0)

now apply the transformations by

using amplitude to multiply y value by 3

and then the phase shift move x value pi/4 to each coordinate

which changes it to

(pi/4,0),(3pi/4,3),(5pi/4,0),(7pi/4,-3),(9pi/4,0)

i hope this helps u
