integral of 1/((196+x^2)^{3/2)}

\int \frac{1}{( 196 + x ^{2} ) ^{\frac{3}{2}}} d x

\frac{x}{196 ( 196 + x ^{2} ) ^{\frac{1}{2}}} + C

Solution steps

\int \frac{1}{( 196 + x ^{2} ) ^{\frac{3}{2}}} d x

Apply Trigonometric Substitution

: \int \frac{1}{196 sec ( u )} d u

= \int \frac{1}{196 sec ( u )} d u

Take the constant out:

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

= \frac{1}{196} \cdot \int \frac{1}{sec ( u )} d u

Rewrite using trig identities

= \frac{1}{196} \cdot \int cos (u) d u

Use the common integral:

\int cos (u) d u = sin (u)

= \frac{1}{196} sin (u)

Substitute back

u = arctan (\frac{1}{14} x)

= \frac{1}{196} sin (arctan (\frac{1}{14} x))

Simplify

\frac{1}{196} sin (arctan (\frac{1}{14} x)) : \frac{x}{196 ( 196 + x ^{2} ) ^{\frac{1}{2}}}

= \frac{x}{196 ( 196 + x ^{2} ) ^{\frac{1}{2}}}

Add a constant to the solution

= \frac{x}{196 ( 196 + x ^{2} ) ^{\frac{1}{2}}} + C

x \to - 1 lim (g (x))

15 e^{3 x}

x \to 3 lim (x)

y^{^{''}} - 4 y^{^{'}} + 4 y = 0, y (0) = 12, y^{^{'}} (0) = - 3

\int (\frac{1}{x ^{2}} - \frac{1}{x x} + 5) d x
