## Homework Statement

i have the vector m(x(t), y(t)) = r = (s^t cos(t), e^t sin(t)) and want to find the line integral of it

## Homework Equations

1. [tex]\int m \centerdot r' dt[/tex]

2. [tex]\int |m| |r'| dt[/tex]

## The Attempt at a Solution

the answer is sqrt(2)/2 (e^pi - 1). when i do the problem the first way, i do not get the sqrt(2)

When i do the problem the first way, the answer is wrong, but when i do it the second way, it is correct.

is the first way even correct? i am told it is, but wolfram alpha is agreeing with me
