Evaluate ModifyingBelow Integral from nothing to nothing With Upper C xy dx plus left parenthesis x plus y right parenthesis dy

Zepler [3.9K]

Parameterize the curve by

$\begin{cases}x(t)=t\\y(t)=4t^2\end{cases}$

with $-3\le t\le1$ . Then

$\displaystyle\int_Cxy\,\mathrm dx+(x+y)\,\mathrm dy$

$=\displaystyle\int_{-3}^14t^3\,\mathrm dt+(t+4t^2)(8t\,\mathrm dt)$

$=\displaystyle\int_{-3}^1(8t^2+36t^3)\,\mathrm dt=\boxed{-\frac{1936}3}$
