integral of 3/(sqrt(4-x^2))

\int \frac{3}{4 - x ^{2}} d x

3 arcsin (\frac{1}{2} x) + C

Solution steps

\int \frac{3}{4 - x ^{2}} d x

Take the constant out:

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

= 3 \cdot \int \frac{1}{4 - x ^{2}} d x

Apply Trigonometric Substitution

: \int 1 d u

= 3 \cdot \int 1 d u

Integral of a constant:

\int a d x = a x

= 3 \cdot 1 \cdot u

Substitute back

u = arcsin (\frac{1}{2} x)

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

Simplify

= 3 arcsin (\frac{1}{2} x)

Add a constant to the solution

= 3 arcsin (\frac{1}{2} x) + C

\frac{d}{d θ} (θ - sin (θ))

x \to 0 lim (\frac{1}{sin ( x )})

\frac{\partial}{\partial x} (\frac{y}{( x + y ) ^{2}})

\frac{d}{d x} (6 x^{2} - x^{3})

7 x^{2} - x^{3}
