Graphing sinusoidal functions khan academy
WebSo the horizontal stretch is by factor of 1/2. Since the horizontal stretch is affecting the phase shift pi/3 the actual phase shift is pi/6 to the right as the horizontal sretch is 1/2. cos (2x-pi/3) = cos (2 (x-pi/6)) Let say you now want to sketch cos (-2x+pi/3). Remember that cos theta is even function. A function is even if f (-x) = f (x). WebSal introduces the main features of sinusoidal functions: midline, amplitude, & period. He shows how these can be found from a sinusoidal function's graph. Created by Sal Khan.

WebThe heart of the wave equations as David described them are trigonometry functions, sine and cosine. Trig functions take angles as arguments. The most natural units to express angles in are radians. The circumference of a circle = π times its diameter. The diameter is 2 times the radius, so C = 2πR. Now when the radius equals 1, C = 2π. Web17.1. A SPECIAL CLASS OF FUNCTIONS 235 sinusoidal function will oscillate. Notice, the points where the sinu-soidal function has a maximum value lie on the line y = D+A. …

WebIt occurs at values where the function is undefined, in this case where its denominator is zero. For tangent, that would be at values of x that make cos (x) = 0 --- in other words, at x = 90 degrees and at x = 270 degrees for 0 <= x <=360.
