2D Vector Calculator

Add, subtract, and compute the dot product, cross product magnitude, and angle between two 2D vectors.

Vector Results

2D Vector Operations for vectors A = (Ax, Ay) and B = (Bx, By):

Addition: A + B = (Ax + Bx, Ay + By)

Subtraction: A − B = (Ax − Bx, Ay − By)

Dot Product: A · B = Ax×Bx + Ay×By

Cross Product Magnitude (2D): |A × B| = Ax×By − Ay×Bx

This is the z-component of the 3D cross product and equals the area of the parallelogram formed by the two vectors.

Angle Between: θ = arccos((A · B) / (|A| × |B|))

Magnitude: |A| = √(Ax² + Ay²)
