Finding_amplitude_and_midline_of_sinusoidal_functions_from_their_formulas
Learn how to find the amplitude and the midline of the graph of a sinusoidal function from its formula. For example, find the amplitude and the midline of f(x)=3*sin(2x-1)+5.
Learn how to draw the graph of sinusoidal functions. For example, draw the graph of f(x)=-2*cos(πx)-7.
The_graphs_of_sine_cosine_and_tangent
Learn how the graphs of y=sin(θ), y=cos(θ), and y=tan(θ) look, using the unit circle definition of the functions.
Constructing_sinusoidal_functions
Learn how to find the formula of a sinusoidal function from its graph or a few selected features. Model real-world situations with sinusoidal functions.
Introduction_to_amplitude_midline_and_extrema_of_sinusoidal_functions
Learn about very important features of sinusoidal functions: the amplitude and the midline. Learn how they relate to the extremum points of the function.
Period_of_sinusoidal_functions
Learn about the period of sinusoidal functions: how it relates to extremum points and the midline, and how to find it from the formula of the function. For example, find the period of f(x)=3*sin(2x-1)+5.
