integral of (17.6x)/(sqrt(17.6x^2+1))

\int \frac{17.6 x}{17.6 x ^{2} + 1} d x

1 17.6 x^{2} + 1 + C

Solution steps

\int \frac{17.6 x}{17.6 x ^{2} + 1} d x

Take the constant out:

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

= 17.6 \cdot \int \frac{x}{17.6 x ^{2} + 1} d x

Apply u-substitution

= 17.6 \cdot \int \frac{1}{35.2 u} d u

Take the constant out:

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

= 17.6 \cdot \frac{1}{35.2} \cdot \int \frac{1}{u} d u

Simplify

= 17.6 \cdot 0.02840 \dots \cdot \int \frac{1}{u} d u

Apply the Power Rule

= 17.6 \cdot 0.02840 \dots \cdot 2 u^{\frac{1}{2}}

Substitute back

u = 17.6 x^{2} + 1

= 17.6 \cdot 0.02840 \dots \cdot 2 (17.6 x^{2} + 1)^{\frac{1}{2}}

Simplify

17.6 \cdot 0.02840 \dots \cdot 2 (17.6 x^{2} + 1)^{\frac{1}{2}} : 1 17.6 x^{2} + 1

= 1 17.6 x^{2} + 1

Add a constant to the solution

= 1 17.6 x^{2} + 1 + C

\int tan (11 x) sec^{2} (11 x) d x

\int 5 e^{4 x} cos (x) d x

\int \frac{x + 8}{x ^{2} + x + 2} d x

\int \frac{x ^{2}}{( 7 + x ^{3} ) ^{2}} d x

\int \frac{x ^{3} + 4}{x ^{5} + 14 x ^{3} + 40 x} d x
