Tangent Line of a Vector Function: The graph of a parametric equation of the vector form r(t) = (x(t) , y(t), z(t)) represents a curve in space. Then, to find the equation of its tangent line, we must calculate the derivative of...
A parametric curve is given by r(t) = (50t, 15t^2, 3t^3). At t = 1, find the unit tangent and the unit normal vectors T(1) and N(1). Consider the vector function given below. r (t) = < 8 t^2, sin (t) - t cos (t), cos (t) + t...
The derivative of the vector function will give the tangent vector function. It is an application of derivatives. A tangent vector to a curve with its magnitude equal to unity is known as the unit tangent vector. The magnitude of a vector v...
The method of the invention includes determining a circular arc (CAR) passing through three discretely given consecutive points (P. sub.i-1, P. sub.i, P.sub.i+1), determining a tangent vector of a tangent line contacting the circular arc (CAR) at the central point (P.sub.i) of thes...
