x = tan t The parametric equations represent a curve. ly= cos t A. Write this as a vector-valued function r(t). B. Calculate r'(t) for the function you wrote in part A. What is the parameter value at the point (1,4) on the curve? D. Use your answers from part B and C to find the unit tangent vector T at the point (1,,) on the curve.
