Find the unit tangent vector T(t) and find a set of parametric equations for the line tangent to the space curve at point P. r(t) = (3 cost, 3 sin t, 3), P(\\{. VZ: 3) Part 1 of 5 The unit tangent vector T(t) at t is defined as follows: T(t) = - r't | r'(t). r'(t) # 0 First find the derivative of r(t). r'(t) = (-3 sin (t) ,3 cos(t),0 (-3 sin(t), 3 cos(t), 0) Part 2 of 5 Now find the magnitude of r'(t). [|~'(t) |) = (-3 sin t)2 + (3 cos t)2 + (0)2 = V 9 sin2 t + 9 cost = 3 4 P 3 Part 3 of 5 The unit tangent vector T(t) at t is as follows: T(t) = (-3 sin t, 3 cos t, 0) 3 (-3 sin (t),3 cos(t),0) (-3 sin(t), 3 cos(t), 0) Part 4 of 5 Verify that t = # at the point P( 7, 7/7, 3). That is, evaluate r(#). Find the unit tangent vector at t = It.
