Unit vector 2D

Determine coordinates of unit vector to vector AB if A[-6; 8], B[-18; 10].

Correct answer:

x =  -0.99
y =  0.16

Step-by-step explanation:

Δx=18+6=12 Δy=108=2 \vectAB=(12;2) \vectAB=Δx2+Δy2=12.17 x=Δx\vectAB=0.99
y=Δy\vectAB=0.16



Did you find an error or inaccuracy? Feel free to write us. Thank you!

Tips to related online calculators
Line slope calculator is helpful for basic calculations in analytic geometry. The coordinates of two points in the plane calculate slope, normal and parametric line equation(s), slope, directional angle, direction vector, the length of the segment, intersections of the coordinate axes, etc.
Our vector sum calculator can add two vectors given by their magnitudes and by included angle.
Pythagorean theorem is the base for the right triangle calculator.
