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). WebGraphing sinusoidal functions Construct sinusoidal functions Google Classroom The graph of a sinusoidal function intersects its midline at (0,1) (0,1) and then has a maximum point at \left (\dfrac {7\pi} {4},5\right) ( 47π,5). Write the formula of the function, where x x is entered in radians. f (x)= f (x) = Stuck?

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.
