Horizontal compression and multiple solutions
When a trig functions has been horizontally compressed eg y = Cos(3x) then there will be multiple solutions (usually 2 solutions in the range 0 to 360 degrees) or 0 < x < 2π

Horizontal Translation
The basic trig functions can be translated horizontally eg y = Tan(x + 1.2) Solve the equivalent function y = Tan(A) where 'A' = x + 1.2 Solving two step problems involving horizontal translation using the graph method and unit circle method

Graphing Ex 35.02 #9 to 13, Solving Ex 35.04 
p158 & p156 
Multiply x
by a number (n) produces 'n' cycles in 360°
(or 2pi) 


Adding a
constant to 'x' translates the graph horizontally
