$$\vec r_1(t) = (t^3, t + 1), t ∈ [0, 1] $$
$$\vec r_2(t) = (t^6, t^2 + 1), t ∈ [0, 1]$$
How can I show that these two parameterizations represent the same line in plane?
Thought that maybe line integral would be the way, however I am not given any $f(x,y,z)$ function to integrate over. When using $f(x,y,z) = 1$ the integral becomes different.
