Place value is where the number is placed and value is what that place is called

Substitute $u=x^2+4$ and $du=2x\,dx$ . Then the integral transforms to

$\displaystyle \int \frac{x\,dx}{(x^2+4)^3} = \frac12 \int \frac{du}{u^3}$

Apply the power rule.

$\displaystyle \int \frac{du}{u^3} = -\dfrac1{2u^2} + C$

Now put the result back in terms of $x$ .

$\displaystyle \int \frac{x\,dx}{(x^2+4)^3} = \frac12 \left(-\dfrac1{2u^2} + C\right) = -\dfrac1{4u^2} + C = \boxed{-\dfrac1{4(x^2+4)^2} + C}$

Which is not a step in finding the scale factor of dilation

mariarad [96]

1)To find a Scale factor of Dilation, about the origin

We have

Pre-mage Image

(x, y) k(x,y)

For example

Pre-image Image

(2,4) 2(2,4) = (4,8)

2)When it's not about the origin then we have to count from the Projection Point

Having said this, ex

Which is not a step

We can divide the x value of the image over the pre-image, not the way around.

In the example, I've given if we divide the pre-image over the image value we would have found a scale factor of 1/2. In the example, The scale factor was the inverse: 2
