Consider an arbitrary ellipse x 2 a 2 + y 2 b 2 = 1. (Assume a, b > 0.) (a) Find a parametrization of the ellipse using the d
uysha [10]

Answer:

α(t) = (-a*Sin(t), b*Cos (t))    where t ∈ [0, 2π]

Step-by-step explanation:

Given an arbitrary ellipse (x²/a²) + (y²/b²) = 1       (a, b > 0)

The parametrization can be as follows

x = -a*Sin(t)

y = b*Cos (t)

then

α(t) = (-a*Sin(t), b*Cos (t))    where t ∈ [0, 2π]

If  t = 0

α(0) = (-a*Sin(0), b*Cos (0)) = (0, b)

If  t = π/2

α(π/2) = (-a*Sin(π/2), b*Cos (π/2)) = (-a, 0)

If  t = π

α(π) = (-a*Sin(π), b*Cos (π)) = (0, -b)

If  t = 3π/2

α(3π/2) = (-a*Sin(3π/2), b*Cos (3π/2)) = (a, 0)

If  t = 2π

α(2π) = (-a*Sin(2π), b*Cos (2π)) = (0, b)

We can see the sketch in the pic.

The sides of a quadrilateral are x,x+3,x+4,x+5. it’s perimeter is 52, find the lengths of the sides
wariber [46]

Answer: 10 , 13 , 14 , 15

Step-by-step explanation:

To find the perimeter of a quadrilateral , we will add all its side , that is

Perimeter = x + x + 3 + x + 4 + x + 5

That is

52 = x + x + 3 + x + 4 + x + 5

52 = 4x + 12

subtract 12 from both sides

40 = 4x

divide through by 4

x = 10

therefore , the lengths of the sides are

10 , 10+3 , 10 + 4 , 10 + 5 , that is

10 , 13 , 14 , 15
