Homework Statement
Let L1 be the tangent line to r(t) at the point t = a and let L2 be the tangent line where t = b. Find the equation of the lines L1. Find the equation of the lines L1 and L2 and find the points of intersection.
r(t) = <f(t), g(t), h(t)>

Homework Equations
The Attempt at a Solution
I just wanted to tell you guys my thought process and would you correct me wherever I am wrong. The question has more to it, but the computation would be menial. I'm just having trouble with what vectors to use and all that stuff.
Steps I would take:
-r(a) would give me a point on L1 and r(b) would give me a point on L2.
-find T(t)
-find T(a) and T(b)
-for L1, the equation of line would be (f(a), g(a), h(a)) + T(a)t
-same step for L2 as L1
-find if there is an intersection by setting the parameters of x,y, and z of the lines equal
Am I using the correct vector, T(t), for the second step?
