2x+4y=12 put it on y=mx+b

morpeh [17]

we need to get y alone so subtract 2x from both sides of the equation

2x+4y=12

-2x -2x

-----------------------

4y=-2x+12 now divide both sides by 4

y = -2x/4 +12/4

y = -1/2 x +3

My attempts at solving this integral keep failing... I'd really appreciate some help :)

$\bf \displaystyle \int \cfrac{csc^2(x)}{1+cot(x)}\cdot dx\\\\
-----------------------------\\\\
u=1+cot(x)\implies \cfrac{du}{dx}=-csc^2(x)\implies \cfrac{du}{-csc^2(x)}=dx\\\\
-----------------------------\\\\
\displaystyle \int\cfrac{csc^2(x)}{u}\cdot \cfrac{du}{-csc^2(x)}\implies -\int \cfrac{1}{u}\cdot du
\\\\\\
-ln|u|+C\implies -ln|1+cot(x)|+C$
