§4.6B: Graphing Trig Functions Transformations Equation: 𝒚=𝑨 𝐭𝐫𝐢𝐠 𝐟𝐮𝐧𝐜𝐭𝐢𝐨𝐧 𝑩 𝒙−𝑪 +𝑫 𝑨 is the amplitude 𝒂: vertically stretches by a factor of 𝒂, 𝟏 𝒂 : Vertically compresses by a factor of 𝟏/𝒂 𝑩 is the period or frequency Period equation: 𝟐𝝅 𝑩 for sine and cosine, 𝝅 𝑩 for tangent 𝑩: phase compresses by a factor of 𝝅 𝑩 𝟏 𝑩 : phasely stretches by a factor of 𝒃 𝑪 is the phase shift If there no GCF taken out, divide the coefficient 𝑬. 𝑫 is the vertical shift F. Frequency is defined as the number of cycles per second 2/22/2019 5:17 PM §4.6B: Graphing Trig Functions

§4.6B: Graphing Trig Functions Steps Identify 𝑨, 𝑩, 𝑪, and 𝑫 from the equation, 𝒚=𝑨 𝐭𝐫𝐢𝐠 𝑩 𝒙−𝑪 +𝑫 Identify the phase shift Period: 𝟐𝜋 𝑩 or 𝜋 𝑩 (for Tan and Cot only) Use the period to identify the spacing 1. Anchor Point Equation: 𝑷𝒆𝒓𝒊𝒐𝒅 𝟒 Start with the phase shift as the middle of the trig table (at the origin) and apply the spacing before and after 2/22/2019 5:17 PM §4.6B: Graphing Trig Functions
