r(t) = (cos5t, sin5t)

T(pi/4) = ( , )

r(t) = (t^2, t^3)

T(1) = ?

r(t) = e^5t i + e^-1t j + t k

T(2) = ? i+ ? j+ ? k

now the to find it i use r'(t)/lr'(t)l

I did that, but i get wrong answers i don't know what I am doing wrong because all i c is that is how u find the unit tangent vectors... someone please help me and explain what u did.. thanks alot!
