∫C xydx+(x-y)dy; C is from (0,0) to (2,0) and (2,0) to (3,2).
I look at this and I dont even know where to start.-Break C into two segments:
(i) (0, 0) to (2, 0) via x = 2t, y = 0 for t in [0, 1].

(170*x*sin(170*x)+cos(170*x))/340
Integrating x*sin(85*x) I get
(sin(85*x)-85*x*cos(85*x))/7225

You want the numbers to be roughly equ
Form a polynomial f(x) with real coefficients having the given degree and zeros.
Degree: 4; Zeros: -4+2i; -3 multiplicity 2.
It asks me to enter the polynomial.
I got this...f(x) = a(x^4-2x^3-19x^2+
And can you please show how you got your answer ?
Thank You xXx-When you have a fraction raised to a - power, the rule is flip the fraction and write the power as a +
(5/6)^1-Power of -1 gives you 1

0 = 6x^2 + 512 / x
Wheres my mistake?
-512 / x = 6x^2
-512 = 6x^3
-512 / 6 = x^3
(-512 / 6)^(1/3) = x
4.40 = x
Note, the answer must be positive because were dealing with square feet.
