How do you plot a sin function with vertical shift?

[ogb0004 (Livia Barrett)]

Basically, I want to plot 8.21Sin(x)+20.3 but Mathematica won’t seem to allow a vertical shift in the Plot sin function. Please help!!

Hi Livia

It would help if you posted the code you tried and explain what you mean by “Mathematica won’t seem to allow a vertical shift”. Is this what you are looking for?

Plot[8.21 Sin[x] + 20.3, {x, 0, 2 Pi},
 AxesOrigin -> {0, 0},
 PlotTheme -> "Detailed"]

Remove AxesOrigin -> {0, 0} and compare. WL has adjusted the origin so the plot is more “centered”, but it is still offset.
