Dear friend:
The reason that you can't change it's y ticks from {-1,0,1} to
{-2,0,2} is that you exceed the range you plot . So , we have to
broaden the plot range if you want to use the ticks {-2,0,2}. i.e.
Plot[Sin[x], {x, 0, 2 Pi}, Frame -> True,
FrameTicks -> {{0, Pi/2, Pi, 3 Pi/2, 2Pi}, {-2, 0, 2}},
PlotRange -> {-2, 2}]
This is the key to the problem . I hope this helps you.
