a. Write and simplify the integral that gives the arc length of the following curve on the given integral. b If necessary, use t
WINSTONCH [101]

Answer:

\int\limits^{\pi/2} _0 (1+4cos^{2} (2x)dx

Step-by-step explanation:

Arc length is calculated by dividing the arcs in to small segments ds

By pythagoren theorem

ds^2=dx^2+dy^2

then integrate ds to get arc length.

We are given a function as

y = sin 2x in the interval  [0, pi/2]

To find arc length in the interval

Arc length s =\int\limits^{\pi/2} _0 {1+y'^2} \, dx \\=\int\limits^{\pi/2} _0 (1+4cos^{2} (2x) )dx

Hence arc length would be

B) \int\limits^{\pi/2} _0 (1+4cos^{2} (2x)dx

Answer:

y = 0, -4

Step-by-step explanation:

1) Factor out the common term 3y.

3y(y + 4) = 0

2) Solve for y.

<em><u>y</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>0</u></em><em><u>,</u></em><em><u> </u></em><em><u>-4</u></em>

galben [10]

Answer: 30

Step-by-step explanation:

Example

x=y

x+z=y+z

If we subtract the same number from both sides of an equation, both sides will remain equal.

Example

x=y

x−z=y−z

If we divide both sides of an equation by the same number, both sides will remain equal.

Example

x=y

x÷z=y÷z

If we multiply both sides of an equation  by the same number, both sides will remain equal.

x=y

x⋅z=y⋅z
