What is the geometric meaning of dot product?

The dot product of two vectors is given by, 

            straight A with rightwards arrow on top times straight B with rightwards arrow on top space equals space AB space cosθ space equals space straight A left parenthesis straight B space cosθ right parenthesis 

Dot product is a scalar quantity. 



Bcosstraight theta is the magnitude of component straight B with rightwards harpoon with barb upwards on top in the direction of A with rightwards harpoon with barb upwards on top 

straight A with rightwards harpoon with barb upwards on top. B with rightwards harpoon with barb upwards on top space equals space left parenthesis M a g n i t u d e space o f space v e c t o r space A with rightwards harpoon with barb upwards on top right parenthesis space left parenthesis m a g n i t u d e space o f space c o m p o n e n t space o f space B with rightwards harpoon with barb upwards on top space i n space t h e space d i r e c t i o n space o f space A with rightwards harpoon with barb upwards on top space right parenthesis
