Tangent, Normal, Binormal & Torsion Problem (HELP)

[ryanlanuza12]

hello, a newbie here!

this is my first time joining a forum and i don't know what to write to this thread. so i'll be direct to the point, i really need someone to help me solve and explain this problem:

given:
x = t
y = t²
z = t³

required:
T=?
N=?
B=?
torsion=?
curvature= optional

i'm kinda confused in getting the N & B. i'm sorry, i'm really bad at this and my english sucks. THANK YOU SO MUCH IN ADVANCE FOR THE PERSON WHO WILL HELP ME

Did the instructor and the textbook not cover this material? Then you'll need lessons, which obviously we cannot provide here. So try some of these online lessons instead.

given: x = t, y = t², z = t³

required:
T=?
N=?
B=?
torsion=?
curvature= optional

After you've studied at least two of the lessons at the link, please attempt to apply the indicated formulas. If you get stuck, you can then reply with a clear listing of what you tried (including the formulas you tried plugging in to) and how far you got. Thank you!

To start with do you know what the words, "Tangent", "Normal", and "Binormal" mean? Their definitions should give you a start on this problem. Do you know the difference between "a normal vector" and "the unit normal vector"? After you have four "a normal vector" you will need to divide by its length to find the "unit normal vector". Can you do that? That's going to be a pretty complicated result so perhaps you are saying you are having difficulty after that- but we need to know exactly what you can do and where you have difficulty.
