comment Line integral segment of parabola
@user131040 please be more specific, i am not telling you the answer. But will comment on what you are doing exactly if you tell me the steps you took. What are you using for $x,y$ and which integral are you taking?

@user131040 You must express them in terms of $t$, as we defined when we parameterized the curve.

comment Is $(A+B)^2 = A^2 + B^2$ if $A$ and $B$ are matrices
Moreover, you proved OP's statement is true iff $AB = -BA$.
