How to Calculate angle between two lines given direction ratios of that two lines w.r.to x, y & z axis?
angle between two lines given direction ratios of that two lines w.r.to x, y & z axis calculator uses Angle A=
acos(((direction ratio 1 of line1*direction ratio 1 of line2)+(direction ratio 2 of line1*direction ratio 2 of line2)+(direction ratio 3 of line1*direction ratio 3 of line2))/(sqrt((direction ratio 1 of line1)^2+(direction ratio 2 of line1)^2+(direction ratio 3 of line1)^2))*(sqrt((direction ratio 1 of line2)^2+(direction ratio 2 of line2)^2+(direction ratio 3 of line2)^2))) to calculate the Angle A, Angle between two lines given direction ratios of that two lines w.r.to x, y & z axis is defined as the angle formed by two lines corresponding to given direction ratios of two lines. Angle A and is denoted by ∠A symbol.
How to calculate angle between two lines given direction ratios of that two lines w.r.to x, y & z axis using this online calculator? To use this online calculator for angle between two lines given direction ratios of that two lines w.r.to x, y & z axis, enter direction ratio 1 of line1 (a1), direction ratio 1 of line2 (a2), direction ratio 2 of line1 (b1), direction ratio 2 of line2 (b2), direction ratio 3 of line1 (c1) and direction ratio 3 of line2 (c2) and hit the calculate button. Here is how the angle between two lines given direction ratios of that two lines w.r.to x, y & z axis calculation can be explained with given input values -> 69.71702 =
acos(((0.2*0.4)+(0.5*0.2)+(0.7*0.44))/(sqrt((0.2)^2+(0.5)^2+(0.7)^2))*(sqrt((0.4)^2+(0.2)^2+(0.44)^2))).
