The script below will calculate the length and coordinates of vector b's projection on vector a, and the angel between them

Vector a's coordinates:

Enter X1 :

Enter Y1 :

Vector b's coordinates:

Enter X2 :

Enter Y2 :



The length of vector a is:
The length of vector b is:

The angel between vector a and vector b is:

The length of b's projection (ba) on vector a is:

The unit vector (ea's) coordinates:
eax

eay

The coordinates of b's projection on a (ba's coordinates):
bax (ba*eax)

bay (ba*eay)
