Find parametric equations for the tangent line to r(t) =< t^2- t + 1, t , sin(t) > at the point (1,0, 0).
found the derivative of r(t) to be r'(t) <2t-1,1,cos(t)> but not sure what to do with that. And he point (1,0,0) occurs at t=0 help please? :]
Put \(t=0\) into the expression for \(r'(t)\) and you will get a tangent vector in your point. Hope you can write an equation of the line if you know its directing vector and the point throught it.
Ahh that makes a lot of sense! Thank you~
Can you write an answer here?
