integral of (10)/(sqrt(9-16x^2))

\int \frac{10}{9 - 16 x ^{2}} d x

\frac{5}{2} arcsin (\frac{4}{3} x) + C

Solution steps

\int \frac{10}{9 - 16 x ^{2}} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 10 \cdot \int \frac{1}{9 - 16 x ^{2}} d x

Apply Trigonometric Substitution

= 10 \cdot \int \frac{1}{4} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 10 \cdot \frac{1}{4} \cdot \int 1 d u

Integral of a constant:

\int a d x = a x

= 10 \cdot \frac{1}{4} \cdot 1 \cdot u

Substitute back

u = arcsin (\frac{4}{3} x)

= 10 \cdot \frac{1}{4} \cdot 1 \cdot arcsin (\frac{4}{3} x)

Simplify

10 \cdot \frac{1}{4} \cdot 1 \cdot arcsin (\frac{4}{3} x) : \frac{5}{2} arcsin (\frac{4}{3} x)

= \frac{5}{2} arcsin (\frac{4}{3} x)

Add a constant to the solution

= \frac{5}{2} arcsin (\frac{4}{3} x) + C
