Moment distribution method and cannes method

determination of metal to ligand ratio by slope ratio method

indirect is not a direct course direct slope is an improved method of a wave of lazer

sobel is the first derivative method that is used to detect edges,, while laplace method is the 2nd derivative method that is used to detect the change of slope.

flattening of slope is generally a method of cutting the hill slope in the shape of steps. these steps being horizontal instead of slopey is better to check erosion.
