Episode 8 — Trigonometric Functions

Effect of q on y=tan x + q

Learners will be able to:

• Identify the effect of adding a constant (q) to the function y = tan x. • Describe how the graph of y = tan x is shifted when q is added to the equation. • Sketch the graph of y = tan x + 1 by plotting key points and joining them in the shape of the tangent curve.
