integral of 1/(sqrt(9-y^2))

\int \frac{1}{9 - y ^{2}} d y

arcsin (\frac{1}{3} y) + C

Solution steps

\int \frac{1}{9 - y ^{2}} d y

Apply Trigonometric Substitution

: \int 1 d u

= \int 1 d u

Integral of a constant:

\int a d x = a x

= 1 \cdot u

Substitute back

u = arcsin (\frac{1}{3} y)

= 1 \cdot arcsin (\frac{1}{3} y)

Simplify

= arcsin (\frac{1}{3} y)

Add a constant to the solution

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

\frac{1}{( z ^{2} + 1 ) ^{2}}

\frac{\partial}{\partial x} (lo g_{10} (2 x))

e^{- \frac{1}{y ^{3}}}

\frac{d y}{d x} = \frac{2 y ^{4} + x ^{4}}{x y ^{3}}

\frac{d ^{3}}{d x ^{3}} (x^{5} e^{x})
