Question 1189943
<br>
Put each equation in standard form:<br><pre>
y=(a)(sin(b(x-c)))+d<br>
amplitude: a
period: (2pi)/b
phase shift (horizontal shift): c
vertical shift: d<br>
1. y=(1/4)sin(2x)  -->  y=(1/4)(sin(2(x-0)))+0  a=1/4; b=2; c=0; d=0<br>
or y=(a)(cos(b(x-c)))+d<br>
2. y=cos(2x)-5  -->  y=(1)(cos(2(x-0)))+(-5) a=1; b=2; c=0; d=-5<br></pre>
