The fact tells us that this line integral should be the same as the second part ( ie zero) However, let's verify that, plus there is a point we need to make here about the parameterization Here is the parameterization for this curve C 3 → r ( t) = ( 1 − t) 1, 1 t − 1, 1 = 1 − 2 t, 1 for 0 ≤ t ≤ 1 Now, using Green's theorem on the line integral gives, ∮ C y 3 d x − x 3 d y = ∬ D − 3 x 2 − 3 y 2 d A ∮ C y 3 d x − x 3 d y = ∬ D − 3 x 2 − 3 y 2 d A where D D is a disk of radius 2 centered at the origin Since D D is a disk it seems like the best way toThe base is the region enclosed by y = x 2 y = x 2 and y = 9 y = 9 Slices perpendicular to the xaxis are right isosceles triangles The intersection of one of these slices and the base is the leg of the triangle 73 The base is the area between y = x y = x and y = x 2 y = x 2

The line x+y=2 cuts the parabola
The line x+y=2 cuts the parabola- Prove that the curves x = y 2 and xy = k cut at right angles if 8k 2 = 1 Hint Two curves intersect at right angle if the tangents to the curves at the point of intersection are perpendicular to each other Example 2 y = x 2 − 2 The only difference with the first graph that I drew (y = x 2) and this one (y = x 2 − 2) is the "minus 2" The "minus 2" means that all the yvalues for the graph need to be moved down by 2 units So we just take our first curve and move it down 2 units Our new curve's vertex is at −2 on the yaxis

Rewrite as x^22xy=0 This is a quadratic equation in variable x Don't be confused, I'm just pointing out that we will temporarily be thinking of y as a constant (a number) We would solve by factoring if we could, but we can't so we'll use the quadratic formula, which says that the solutions to 2x^2 bx c = 0 are x=(bsqrt(b^24ac))/(2a)This is the 3rd video I sent to a graduating Grade 12 when her graduation in was cancelled because of COVID19 Her Mom asked those who knew her or taugCalculus Multivariable Calculus Find the area of the finite part of the paraboloid y = x 2 z 2 cut off by the plane y = 25 Hint Project the surface onto the xzplane more_vert Find the area of the finite part of the paraboloid y = x 2 z 2 cut off by the plane y

If so, evaluate https//mathstackexchangecom/q/For positive values of a and b, the binomial theorem with n = 2 is the geometrically evident fact that a square of side a b can be cut into a square of side a, a square of side b, and two rectangles with sides a and bWith n = 3, the theorem states that a cube of side a b can be cut into a cube of side a, a cube of side b, three a × a × b rectangular boxes, and three a × b × bSo, other point where parabola will cut the straight line is when x is 2, in which case y = x^2 = (2)^2 = 4 So, second point is (2, 4)
