Answer:

The integration of \sqrt{16-25x^2} is \frac{x}{2}.{\sqrt{16-25x^2}+\frac{8}{5}.sin^-1(\frac{5x}{4}) +C

Step-by-step explanation:

We have an equation \sqrt{16-25x^2} and we need to integrate it with respect to x on the interval (-4/5,4/5).

So the integration of a given expression can be done as

\int\sqrt{16-25x^2}\\=\int\sqrt{(25(16/25)-x^2).dx}\\=\int5\sqrt{(4/5)^2-x^2}\\=5\int\sqrt{(4/5)^2-x^2}\\

And we know the property of integral as

\int(\sqrt{a^2-x^2}=\frac{x}{2}.\sqrt{a^2-x^2}+\frac{a^2}{2}.Sin^{-1}(\frac{x}{a})+C

The integral becomes

\int\sqrt{16-25x^2} = 5\int\sqrt{(4/5)-x^2} \\=5(\frac{x}{2}.\sqrt{(4/5)^2-x^2}+\frac{16}{25*.2}.Sin^{-1}{\frac{x}{4/5})}\\=\frac{5x}{2}.\sqrt{(16/25-x^2}+\frac{5.8}{25}Sin^{-1}\frac{5x}{4}

By solving carely and properly we get

\int\sqrt{16-25x^2} = \frac{x}{2}.{\sqrt{16-25x^2}+\frac{8}{5}.sin^-1(\frac{5x}{4}) +C

And it is the required solution to the given problem.
