How do you integrate arctan(x dx? i think that if you simplify the integral you get:?

Temka [501]

Integration by parts will help here. Letting $u=\arctan x$ and $\mathrm dv=\mathrm dx$ , you end up with $\mathrm du=\dfrac{\mathrm dx}{1+x^2}$ and $v=x$ . Now

$\displaystyle\int\arctan x\,\mathrm dx=uv-\int v\,\mathrm du$
$\displaystyle\int\arctan x\,\mathrm dx=x\arctan x-\int\frac x{1+x^2}\,\mathrm dx$

For the remaining integral, setting $y=1+x^2$ gives $\dfrac{\mathrm dy}2=x\,\mathrm dx$ , so

$\displaystyle\int\frac x{1+x^2}\,\mathrm dx=\frac12\int\frac{\mathrm dy}y=\frac12\ln|y|+C=\frac12\ln(1+x^2)+C$

Putting everything together, you end up with

$\displaystyle\int\arctan x\,\mathrm dx=x\arctan x-\frac12\ln(1+x^2)+C$

Write the point-slope equation of the line with the given properties. Solve the equation for y. M= -0.25, (12,7)

-Dominant- [34]

Answer:

y = -0.25x + 10

Step-by-step explanation:

Point-slope form is y - y1 = m (x - x1)

Here, y1 is 7, m is -0.25, and x1 is 12

When you plug these values in, you get y - 7 = -0.25 (x - 12)

Now we have to solve for y.

y - 7 = -0.25 (x - 12)

Distribute

y - 7 = -0.25x + 3

Add 7 to both sides

y = -0.25x + 10
