Evaluate the integral f*dr where f(x,y)=<-y,x^2> and c consists of te arc of the parabola y=2x^2 from (-1,2) to (1,2)

d1i1m1o1n [39]

$y=2x^2\implies\mathbf r(x)=\langle x,2x^2\rangle$

$\displaystyle\int_C\mathbf F\cdot\mathrm d\mathbf r=\int_{t=-1}^{t=1}\langle-2x^2,x^2\rangle\cdot\langle1,4x\rangle\,\mathrm dx$
$=\displaystyle\int_{-1}^1(8x^3-2x^2)\,\mathrm dx$
$=-\dfrac43$

(ax + b) × (cx + d) =

Stolb23 [73]

These are easy if you know " FOIL ". That's a procedure that takes you through multiplying two binomials.

FOIL stands for
-- <u><em>F</em></u>irst terms
<span>-- </span><u><em>O</em></u>utside terms
<span>--<em> </em></span><u><em>I</em></u>nside terms
<span>--<em> </em><u><em>L</em></u></span>ast terms

and that's how you keep everything straight while you're doing it.

(ax + b) x (cx + d)

Multiply First terms . . . 'ax' times 'cx' = <em>acx²</em>

Multiply Outside terms . . . 'ax' times 'd' = <em>adx</em>

Multiply Inside terms . . . 'b' times 'cx' = <em>bcx</em>

Multiply Last terms . . . 'b' times 'd' = <em>bd</em>

Now addummup:

(ax + b) x (cx + d) = <em>acx² + adx + bcx + bd</em>

From there, you can look for opportunities to make it look cleaner and prettier ... factoring, combining like terms, etc.
