Episode 12 — Trigonometric Functions

Effect of a on y = a tan x

Learners will be able to:

• Identify the effect of a constant on the graph of y = tan x. • Describe how multiplying the original y-values by a constant affects the graph of y = tan x. • Explain why the range and asymptotes remain unchanged when a constant is multiplied in front of the function y = tan x. • Sketch the graphs of y = 2tan x and compare them to the graph of y = tan x. • Identify how a negative value of 'a' affects the graph of y = tan x.
