integral from 0 to 1 of 1/(sqrt(25-x^2))

\int_{0}^{1} \frac{1}{25 - x ^{2}} d x

arcsin (\frac{1}{5})

Decimal Notation

0.20135 \dots

Solution steps

\int_{0}^{1} \frac{1}{25 - x ^{2}} d x

Apply Trigonometric Substitution

: \int_{0}^{a r c s i n (\frac{1}{5})} 1 d u

= \int_{0}^{a r c s i n (\frac{1}{5})} 1 d u

Integral of a constant:

\int a d x = a x

= [1 \cdot u]_{0}^{a r c s i n (\frac{1}{5})}

Simplify

= [u]_{0}^{a r c s i n (\frac{1}{5})}

Compute the boundaries:

arcsin (\frac{1}{5})

= arcsin (\frac{1}{5})

\int_{0}^{4} x^{2} cos (\frac{nπ x}{4}) d x

\int_{0}^{π} sin (7 x) cos (3 x) d x

\int_{0}^{2 π} (1 - cos (x))^{3} d x

\int_{0}^{2 π} cos^{3} (t) d t

\int_{0}^{\frac{π}{2}} cos^{11} (x) d x
