Question
confused on whether i use the given vectors or if i have to calculate the vectors using the image given
Two vectors are presented as a = 6.0î + 4.5j and b = 5.5î + 2.5j. Find the following. (Hint: For (d), consider the equation a b = ab cos o and the figure below.) Component of b along direction of a is b cos o Multiplying these gives the dot product. Component of q along direction of bis a cos o Or multiplying these gives the dot product.
