1.2-Dot Product Definitions : The dot product of the vectors a and b is given by Dot Product computation formula From the definition, it follows that the angle between two vectors is given by a and b are orthogonal if and only if Orthogonal complements Scalar and Vector projections Work Examples: Find a · b if a = < 3 , 2 > and b = i - 4 j
