Transformation Of Trigonometric Graphs
1. If
: Scaling of graph with a factor of
parallel to the
-axis
2. If
: Scaling of graph with a factor of
parallel to the
-axis, then reflecting of graph in
-axis
For sin & cos: amplitude becomes
For tan: there is no amplitude




2. If




For sin & cos: amplitude becomes

For tan: there is no amplitude

Scaling of graph with a factor of
parallel to the
-axis
For sin & cos: period becomes
For tan: period becomes


For sin & cos: period becomes

For tan: period becomes

Translating of graph by
units parallel to the
-axis
