Someone help me integrate this please >_
NISA [10]
∫( (sinx) / (2 - 3cosx)) dx.

From laws of integration:   ∫ f¹(u) / f(u) du = In(f(u)) + constant.

d/dx (2 - 3cosx) =  0 -3(-sinx) = 3sinx.

1/3d/dx(2 - 3cosx) = (1/3)*3sinx = sinx.

∫ ((sinx) / (2 - 3cosx)) dx.      =  ∫ ((1/3) d/dx (2 - 3cosx) / (2 - 3cosx))dx

= 1/3 ∫ (d/dx (2 - 3cosx) / (2 - 3cosx))dx 

= (1/3)ln(2 - 3cosx) + Constant.

Find the cost of painting a cubical block of side length 3.2 cm, if painting costs $5 per cm2.
SashulF [63]
<h3><u>Answer</u>:- </h3>

\longrightarrow \sf \$ \: 307.2

<h3><u>Solution:-</u></h3>

Since painting is done on outer surface of cubical block we will have to find its surface area which is given by-

\green{ \underline { \boxed{ \sf{Surface \: area  \:of  \:Cube = 6a^2}}}}

  • <u>where a is side of the cube </u>

\begin{gathered}\\\quad \sf Surface \: area  \:of  \:Cube = 6\times(3.2)^2  \\\end{gathered}

\begin{gathered}\\\implies \quad \sf  6\times 3.2\times3.2   \\\end{gathered}

\begin{gathered}\\\implies \quad \sf  61.44 cm^2  \\\end{gathered}

Now,

\maltese \sf Cost  \:of  \:painting \: 1 \: cm² = \$ 5

\sf Cost \: of \: painting \: 61.44  \:cm²=61.44×5

\sf\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad=\$ 307.2

\leadstoThus it would cost $ 307.2 to paint the entire cubical block.
