NeTakaya

-5x - 6y = -21
5x - y =. 84

-7y = 63

y= -9

-5x = -21 - 54

-5x = -75

x = 15

99 POINT QUESTION, AND BRAINLIEST!!!

77julia77 [94]

$\displaystyle\int_{x=1}^{x=14}\frac{1-\cos4x}{4x-\sin4x}\,\mathrm dx$

First, replace $y=4x$ and $\mathrm du=4\,\mathrm dx$ . Then you have

$\displaystyle\frac14\int_{y=4}^{y=56}\frac{1-\cos y}{y-\sin y}\,\mathrm dy$

If we take $z=y-\sin y$ , then immediately we see a differential in the numerator in the form of $\mathrm dz=(1-\cos y)\,\mathrm dy$ . So the integral becomes

$\displaystyle\frac14\int_{z=4-\sin4}^{z=56-\sin56}\frac{\mathrm dz}z$

and evaluates to

$\dfrac14\ln|z|\bigg|_{z=4-\sin4}^{z=56-\sin56}=\dfrac14\left(\ln|56-\sin56|-\ln|4-\sin4|\right)=\dfrac14\ln\left|\dfrac{56-\sin56}{4-\sin4}\right|$

making (A) the correct answer.
