Answer:

The Pythagorean theorem states that: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).

Step-by-step explanation:

The Pythagorean Theorem, a2+b2=c2,a2+b2=c2, is used to find the length of any side of a right triangle

• In a right triangle, one of the angles has a value of 90 degrees

• The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle

• If the length of the hypotenuse is labeled cc, and the lengths of the other sides are labeled aa and bb, the Pythagorean Theorem states

that a2+b2=c2a2+b2=c2 that a2+b2=c2a2+b2=c2

∫c x sin y ds, C is the line segment from (0, 1) to (3, 5)

Mnenie [13.5K]

Parameterize the line segment $C$ by

$\mathbf r(t)=\langle x(t),y(t)\rangle=(1-t)\langle0,1\rangle+t\langle3,5\rangle=\langle3t,1+4t\rangle$

where $t\in[0,1]$ . Then

$\mathrm ds=\|\mathbf r'(t)\|\,\mathrm dt$
$\mathrm ds=\|\langle3,4\rangle\|\,\mathrm dt$
$\mathrm ds=5\,\mathrm dt$

So the integral is

$\displaystyle\int_Cx\sin y\,\mathrm ds=5\int_0^1x(t)\sin y(t)\,\mathrm dt$
$=\displaystyle5\int_0^13t\sin(1+4t)\,\mathrm dt$
$=\dfrac{15}{16}(\sin5-\sin-4\cos5)\approx-2.7516$
