dr The derivative of a vector-valued function F(t) , denoted as '(t) or is dt '(t) lim h0 (t + h) (t) %3D h provide the limit exists: (A) In practice, we use the fact that we can compute derivatives of vector-valued functions by taking the derivative: (Choose one options, and explain why this option makes sense) (a) factor by factor (b) component by component (B) The derivative of vector r' (a) will be a tangent vector to the graph of r(t), which points in the direction of increasing t, provided r' (a) is plotted with its initial point (Choose one options, and provide explanation of why one of this option makes sense) (a) at r(a) (b) at r' (a) (c) in standard position
