Precalculus Accelerated
Trigonometric Graphs Day 8
Tangent/Cotangent Graphs
Date:____________
Warm Up:
Write a secant equation of the graph:
y = _______________________________
Target: Graph the tangent and cotangent with vertical stretching/shrinking, phase shifts and vertical shifts

R:
even, odd or neither?
Conclusions:
y = tan(Bx) has a period of ___________.
We always graph ____________________ of tangent.
Tangent is ___________________ unless there is a __________________.
2.
amp:
y = cot(x)
per:
D:
R:
even, odd or neither?
Conclusions:
y = cot(Bx) has a period of ___________.
We always graph ____________________ of cotangent.
Cotangent is ___________________ unless there is a ___________________.
