Translation
Given
the graph of y = f(x), the following indicate the need for translation:
g(x) =
f(x) + a
g(x) = f(x + a)
 Graph
of y = sin
2x + 0.5
This
graph is obtained by translating the graph of y = sin 2x in the
direction of the positive y-axis by 0.5 units.
Graph
of y = sin
(x + 90o)
This
graph is obtained by translating the graph of y = sin x in the
direction of the negative x-axis by 90o. Note that this curve is
actually the cosine curve.
