Generally, one of the lines is considered to be the horizontal line parallel to the x-axis or the x-axis and the angle it makes with the other line is referred to as the gradient of that line. If the angle between the lines is θ θ then the gradient m= tanθ m = t a n θ. crystal risher dccWebGradient-> {f x, f y, …} specifies explicit components to assume for the gradient vector.
