integral of (3x)/(sqrt(7-25x^4))

\int \frac{3 x}{7 - 25 x ^{4}} d x

\frac{3}{10} arcsin (\frac{5}{7} x^{2}) + C

Solution steps

\int \frac{3 x}{7 - 25 x ^{4}} d x

Take the constant out:

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

= 3 \cdot \int \frac{x}{7 - 25 x ^{4}} d x

Apply u-substitution

= 3 \cdot \int \frac{1}{2 7 - 25 u ^{2}} d u

Take the constant out:

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

= 3 \cdot \frac{1}{2} \cdot \int \frac{1}{7 - 25 u ^{2}} d u

Apply Trigonometric Substitution

= 3 \cdot \frac{1}{2} \cdot \int \frac{1}{5} d v

Take the constant out:

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

= 3 \cdot \frac{1}{2} \cdot \frac{1}{5} \cdot \int 1 d v

Integral of a constant:

\int a d x = a x

= 3 \cdot \frac{1}{2} \cdot \frac{1}{5} \cdot 1 \cdot v

Substitute back

= 3 \cdot \frac{1}{2} \cdot \frac{1}{5} \cdot 1 \cdot arcsin (\frac{5}{7} x^{2})

Simplify

3 \cdot \frac{1}{2} \cdot \frac{1}{5} \cdot 1 \cdot arcsin (\frac{5}{7} x^{2}) : \frac{3}{10} arcsin (\frac{5}{7} x^{2})

= \frac{3}{10} arcsin (\frac{5}{7} x^{2})

Add a constant to the solution

= \frac{3}{10} arcsin (\frac{5}{7} x^{2}) + C
