Hello...i had a question. I would really appreciate it if someone could help me...tnx in advance!
K my question is Find the T(t) , N(t), B(t) for r(t)=<2sint,2cost,t>; t=pie/4
...which are normal vectors, binomial vector and i am not sure about T(T)...anyhow...i have the formula for
T(t)
T(t)=r'(t)/abs(r'(t))
so far i got
r'(t)=2cos,-2sint,1
abs(r'(t)=squarroot(2cos(pie/4)-2sin(pie/4)+1)
so plugging it in for
T(t)=r'(t)/abs(r'(t))
it would be
T(t)=2cos(pie/4),-2sin(pie/4),1/squarroot(2cos(pie/4)-2sin(pie/4)+1
is that right...so once i find T(t)...i would fidn N(t) and B(t) ...but so far i just want to check if what i have it right so far...plz plz plz help me...tnz once again
so plugging that for T(t)
