Apakah peralihan fasa, anjakan menegak berkenaan dengan y = sinx bagi graf y = sin (x-50 ^ circ) +3?

Jawapan:

# "peralihan fasa" = + 50 ^ @, "peralihan menegak" = + 3 #

Penjelasan:

Bentuk standard bagi #color (biru) "fungsi sinus" # adalah.

#color (merah) (bar (ul (| warna (putih) (2/2) warna (hitam) (y = asin (bx + c)

# "where amplitude" = | a |, "period" = 360 ^ @ / b #

# "pergeseran fasa" = -c / b "dan anjakan menegak" = d #

# "here" a = 1, b = 1, c = -50 ^ @ "dan" d = + 3 #

#rArr "shift fasa" = - (- 50 ^ @) / 1 = + 50 ^ @ rarr "shift right" #

# "dan anjakan menegak" = + 3uarr #
