What is the integral of 1/(sqrt(4-(x-2)^2)) ?

The integral of 1/(sqrt(4-(x-2)^2)) is arcsin(1/2 x-1)+C

integral of 1/(sqrt(4-(x-2)^2))

\int \frac{1}{4 - ( x - 2 ) ^{2}} d x

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

Solution steps

\int \frac{1}{4 - ( x - 2 ) ^{2}} d x

Apply u-substitution

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

Apply Trigonometric Substitution

= \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} (x - 2))

Simplify

1 \cdot arcsin (\frac{1}{2} (x - 2)) : arcsin (\frac{1}{2} x - 1)

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

Add a constant to the solution

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

\int \frac{x}{x ^{2} - 2 x - 15} d x

\int 27 x^{7} + 3 x^{5} - 45 x^{3} + 2 x d x

\int cos^{3} (3 x) - cos (3 x) d x

\int \frac{x ^{3}}{x ^{4} cos ^{2} ( ln ( x ) )} d x

\int (\frac{x ^{3} + 5 x ^{2} - 4}{x ^{2}}) d x
