The absolute . is the horizontal line that passes exactly in the middle between the graph's maximum and minimum points. When changing values for displacement, velocity or acceleration the calculator assumes the frequency stays constant to calculate the other two unknowns. Multiplying the whole function by 2 is doubling the amplitude. Here is the graph of a trigonometric function.
