integral of (100)/(sqrt(100-x^2))

\int \frac{100}{100 - x ^{2}} d x

100 arcsin (\frac{1}{10} x) + C

Solution steps

\int \frac{100}{100 - x ^{2}} d x

Take the constant out:

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

= 100 \cdot \int \frac{1}{100 - x ^{2}} d x

Apply Trigonometric Substitution

: \int 1 d u

= 100 \cdot \int 1 d u

Integral of a constant:

\int a d x = a x

= 100 \cdot 1 \cdot u

Substitute back

u = arcsin (\frac{1}{10} x)

= 100 \cdot 1 \cdot arcsin (\frac{1}{10} x)

Simplify

= 100 arcsin (\frac{1}{10} x)

Add a constant to the solution

= 100 arcsin (\frac{1}{10} x) + C

\int x 1 7^{x} d x

\int \frac{1}{2 x - 1} - \frac{1}{2 x + 1} d x

\int (3 x + 1) e^{- x + 1} d x

\int e^{l n (2 - x)} d x

\int 6 x sec^{2} (x^{2}) cos (tan (x^{2})) d x
