I suppose that 90 in your first equation is 90°
90°=(pi/2) radians
y+3= 2sin(3x +90°)
y=2sin(3x +90°)-3
y=2sin(3x +90°)-3 Angle in degres
y= 2sin(3x +pi/2)-3 Angle in radians
In google type:
"function graphs on line"
When you see list of results click on:
rechneronline.de/function-graphs/
When this page be open in blue rectacangle type:
2sin(3x + pi/2)-3
In gray rectacangle type:
sin(x)
Then click option Draw
You will see both graphs
Describe how the graph of y + 3 = 2sin(3x + 90) compares to the graph of y = sin(x)
