10 gru 2013 · The following VBA Function calculates the distance from the point (X,Y) to the straight line. Option Explicit. Function Dist2Line (Y As Double, X As Double, Ys As Variant, Xs As Variant) As Double. 'Distance from the point (X,Y) to a straight line with equation Y=A0+A1*X.
8 paź 2020 · I need to calculate the shortest distance from anyplace on this line to a point (X', Y') elsewhere on the coordinate plane. If this is represented by X' in D1, and Y' in D2, I'm using the formula: =ABS((SLOPE(B1:B10,A1:A10)*D1-D2+INTERCEPT(B1:B10,A1:A10))/SQRT(SLOPE(B1:B10,A1:A10)2 +1)).
Shows how to find the perpendicular distance from a point to a line, and a proof of the formula.
Drop a perpendicular from the point P with coordinates ( x0, y0) to the line with equation Ax + By + C = 0. Label the foot of the perpendicular R. Draw the vertical line through P and label its intersection with the given line S.
To compute the length of a 2D line given the coordinates of two points on the line, you can use the distance formula, adapted for Excel's formula syntax. In the example shown, the formula in G5, copied down, is: =SQRT ( (D5-B5)^2+ (E5-C5)^2) where the coordinates of the two points are given in columns B through E.
Using the perpendicular distance formula, find the equation of the line that passes through the third point and is perpendicular to the line found in step 1. The perpendicular distance from a point (x3, y3) to a line with equation Ax + By + C = 0 is: d = |Ax3 + By3 + C| / sqrt(A^2 + B^2)
Learn how to find the perpendicular distance of a point from a line easily with a formula. For the formula to work, the line must be written in the general form.
