The coefficient ofmust be1 before you can read the horizontal shift.You must factor out the coefficient ofxif it is not 1. * Note: Use of the phrase "phase shift": When used in mathematics, a "phase shift" refers to the "horizontal shift" of a trigonometric graph. While mathematics te...
However, a vertical shift function was not needed. In Figure 4.17, a three-dimensional graph is shown indicating the variation of Fx and Fy with both α and κ. The initial ‘S’ shape of the Fy vs κ curves (at small α) due to the vertical shift function is clearly visible. Sign ...
