# Angle Between Vectors Calculation

An online angles btn two vectors calculation.

 i1+ j1+ k1
 i2+ j2+ k2

## Formula: Angle Between Two Vectors

• r = arccos( ( a1i * a2i ) + ( b1j * b2j ) + ( c1k * c2k ) ) / ( √ (a1i 2 + b1j 2 + c1k 2 ) * √ (a2i 2 + b2j 2 + c2k 2 ) )
•
• Where ,
•     r = Angle Between Two Vectors
•     a1i = i1 Coefficient
•     b1j = j1 Coefficient
•     c1k = k1 Coefficient
•     a2i = i2 Coefficient
•     b2j = j2 Coefficient
•     c2k = k2 Coefficient
