Graphing sinusoidal functions
Learn how to draw the graph of sinusoidal functions. For example, draw the graph of f(x)=-2*cos(πx)-7.
Sal graphs y=2*sin(-x) by considering it as a vertical stretch and a horizontal reflection of y=sin(x).
Sal graphs y=-2.5*cos(1/3*x) by considering it as a vertical stretch and reflection, and a horizontal stretch, of y=cos(x).
Given the formula of a sinusoidal function of the form a*f(bx)+d, draw its graph.
Given the formula of a sinusoidal function of the form a*f(bx+c)+d, draw its graph.
