Step 7. To mark the stair railing, hold it in place, resting along the stairs, and mark it for the angled cut. Pre-drill the landing and treads for the balusters, using a special stair bit that drills the hole and then creates a thread to accept the baluster bolts.
What is interpolation? Interpolation is the process of estimating unknown values that fall between known values. In this example, a straight line passes through two points of known value. You can estimate the point of unknown value because it appears to be midway between the other two points. The interpolated value of the middle point could be 9.5.
mehtamatics = mathematics with a difference. Both, interpolation and extrapolation are used to predict, or estimate, the value of one variable when the value (or values) of other variable (or variables) is known. This is done by extending evaluating the underlying function. For interpolation, the point in question is within the domain of the observed values (there are observations for greater and for smaller values of the variables) wheres for extrapolation the point in question is outside the domain.
