Study Guide Overview
This study guide covers sinusoidal functions, including sine and cosine. It defines sinusoidal functions and explains their key characteristics: period, frequency, midline, amplitude, symmetry (odd and even), oscillation, and concavity. It also emphasizes the relationship between period and frequency and provides tips for identifying the midline.

Hey there, future AP Pre-Calculus master! Let's dive into the world of sinusoidal functions. Think of this as your pre-exam power-up – everything you need, nothing you don't. Let's get started!
#Understanding Sinusoidal Functions
#What are Sinusoidal Functions?
-
A sinusoidal function is any function that looks like a sine or cosine curve – oscillating and periodic. Both sine and cosine functions are sinusoidal, and so are their transformations.
-
Key Idea: The cosine function is just a transformed sine function:
This means the cosine curve is the sine curve shifted to the left by units. Think of it as a horizontal slide! ➡️
