I am doing a TNB-Frame problem and I am currently finding the tangent. The point I am trying to find it at is t=0 and my vector T(t) comes out to be in indeterminate form. So my question is how would I solve for vector T(t).
Nah. I differentiated $\displaystyle R(t)= <cos(t)+t*sin(t),sin(t)-t*cos(t),1>$ into $\displaystyle R'(t)=<t*cos(t),t*sin(t),0>$
My goal is to find vector T(t) which is $\displaystyle R'(t)'/|R'(t)|$
When you do that though you are in indeterminate form. So my question is how would I solve it properly?
