Parametric Equation of a Tangent Line off a Helix
represents the position of a particle on a helix after t seconds, where z is the height of the particle above the ground in meters.
When the particle is 12 meters above the ground, the particle leaves the helix and moves along the tangent line to the helix. Find a parametric equation for this tangent line.
Sorry if I messed up the LaTex, I'm new. So far I have the t will be 3 when it is 12 meters off of the ground and I have this so far for my parametric equation by taking the derivative of the vector:
I'm not sure that this is right at all, and I assume that the tangent line has to cross through the point (3cos(3), 3sin(3),12) and that parametric equation doesn't. Any help would be great, thanks!
