integral of (cos(x))/(sqrt(4-sin^2(x)))

\int \frac{cos ( x )}{4 - sin ^{2} ( x )} d x

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

Solution steps

\int \frac{cos ( x )}{4 - sin ^{2} ( x )} d x

Apply u-substitution

: \int \frac{1}{4 - u ^{2}} d u

= \int \frac{1}{4 - u ^{2}} d u

Apply Trigonometric Substitution

: \int 1 d v

= \int 1 d v

Integral of a constant:

\int a d x = a x

= 1 \cdot v

Substitute back

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

Simplify

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

Add a constant to the solution

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

\int (sec^{2} (x) - 7) d x

f (x) = \frac{3 x}{x - 2}

h \to 0 lim (\frac{( h - 1 ) ^{3} + 1}{h})

f (x) = \frac{1 - 2 x}{3 - x}

\frac{d}{d x} (x + 7)
