Q. Given the equation y=3+4cos⁡(2x)y=3+4\cos(2x), give the equation of the sinuso\＂idal axis
  1. Identifying Sinusoidal Axis: The sinusoidal axis of a function like y=A+Bcos⁡(Cx)y = A + B\cos(Cx) is the horizontal line that represents the average value of the function over one period. To find it, we look at the constant term outside the cosine function.
  2. Analyzing Equation Components: In the equation y=3+4cos⁡(2x)y = 3 + 4\cos(2x), the constant term is 33. This means the sinusoidal axis is the horizontal line y=3y = 3.
