integral of (4-x)/(sqrt(16-x^2))

\int \frac{4 - x}{16 - x ^{2}} d x

4 arcsin (\frac{1}{4} x) + 16 - x^{2} + C

Solution steps

\int \frac{4 - x}{16 - x ^{2}} d x

Expand

\frac{4 - x}{16 - x ^{2}} : \frac{4}{16 - x ^{2}} - \frac{x}{16 - x ^{2}}

= \int \frac{4}{16 - x ^{2}} - \frac{x}{16 - x ^{2}} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{4}{16 - x ^{2}} d x - \int \frac{x}{16 - x ^{2}} d x

\int \frac{4}{16 - x ^{2}} d x = 4 arcsin (\frac{1}{4} x)

\int \frac{x}{16 - x ^{2}} d x = - 16 - x^{2}

= 4 arcsin (\frac{1}{4} x) - (- 16 - x^{2})

Simplify

= 4 arcsin (\frac{1}{4} x) + 16 - x^{2}

Add a constant to the solution

= 4 arcsin (\frac{1}{4} x) + 16 - x^{2} + C

\frac{d}{d x} (r (h, t, x) i g (h, t, x) h t)

\int (x + 1)^{2} \cdot x^{2} d x

f (x) = 5 (9 x^{7} + 3 x^{4} - 2)^{3}

\frac{d}{d x} (3^{x l o g_{2} (x^{4})})

\frac{d}{d x} (ln (n x + 10))
