If you had matrix 1 with dimensions axb and matrix 2 with cxd then it depends on what order you multiply them. Kind of like subtraction where 2-3 = -1 but 3-2=1, it changes the answer. So if you did matrix 1 times matrix 2 then b must equal c in dimensions. dyamond honoreWebSpecifically, when \theta = 0 θ = 0, the two vectors point in exactly the same direction. Not accounting for vector magnitudes, this is when the dot product is at its largest, because \cos (0) = 1 cos(0) = 1. In general, the more two vectors point in the same direction, the bigger the dot product between them will be. dyamond fitnessWebLearn about matrices using our free math solver with step-by-step solutions. crystal palace bootWebThis precalculus video tutorial provides a basic introduction into matrices.
