To determine Show that lim t → t o [ r 1 ( t ) × r 2 ( t ) ] = A × B by using the determinant formula for cross products and the Limit Product Rule for scalar functions. Explanation Consider the vector functions, r 1 ( t ) = f 1 ( t ) i + f 2 ( t ) j + f 3 ( t ) k r 2 ( t ) = g 1 ( t ) i + g 2 ( t ) j + g 3 ( t ) k Consider the limits of vector functions, lim t → t 0 r 1 ( t ) = A lim t → t 0 r 2 ( t ) = B The limits of cross product of vector functions is calculated as follows, lim t → t o [ r 1 ( t ) × r 2 ( t ) ] = lim t → t o | i j k f 1 ( t ) f 2 ( t ) f 3 ( t ) g 1 ( t ) g 2 ( t ) g 3 ( t ) | = | i j k lim t → t o <
