Q. What is the midline equation ofy=10cos(6x−1)−4?y=□
Midline of Trigonometric Function: The midline of a trigonometric function like y=Acos(Bx−C)+D or y=Asin(Bx−C)+D is the horizontal line y=D, where D is the vertical shift of the function.
Vertical Shift and Midline Equation: In the given function y=10cos(6x−1)−4, the value of D is −4. This represents the vertical shift from the origin, which is also the equation of the midline.
