Explanation Given: The curve: r ( t ) = 〈 t , t , 4 − t 2 〉 And the point P : ( 1 , 1 , 3 ) Formula Used: Let C be a smooth curve which makes the representation by r on an open interval I . The unit tangent vector at t is defined as: T ( t ) = r ′ ( t ) ‖ r ′ ( t ) ‖ , r ′ ( t ) ≠ 0 A line L parallel to v = 〈 a , b , c 〉 and passes through the point P ( x 1 , y 1 , z 1 ) is shown by the parametric equation: x = x 1 + a t y = y 1 + b t z = z 1 + c t Calculation: Consider the specified curve: r ( t ) = 〈 t , t , 4 − t 2 〉 Differentiate r ( t ) as follows: r ′ ( t ) = 〈 1 , 1 , − t 4 − t 2 〉 This gives the unit tangent vector as follows: T ( t ) = r ′ ( t ) ‖ r ′ ( t ) ‖ = 1 1 2 + 1 2 + ( − t 4 − t 2 ) 2 〈 1 , 1 , − t
