integral of sin(t^{1/2})

\int sin (t^{\frac{1}{2}}) d t

2 (- t^{\frac{1}{2}} cos (t^{\frac{1}{2}}) + sin (t^{\frac{1}{2}})) + C

Solution steps

\int sin (t^{\frac{1}{2}}) d t

Apply u-substitution

: \int sin (u) \cdot 2 u d u

= \int sin (u) \cdot 2 u d u

Take the constant out:

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

= 2 \cdot \int sin (u) u d u

Apply Integration By Parts

: - u cos (u) - \int - cos (u) d u

= 2 (- u cos (u) - \int - cos (u) d u)

\int - cos (u) d u = - sin (u)

= 2 (- u cos (u) - (- sin (u)))

Substitute back

u = t^{\frac{1}{2}}

= 2 (- t^{\frac{1}{2}} cos (t^{\frac{1}{2}}) - (- sin (t^{\frac{1}{2}})))

Simplify

= 2 (- t^{\frac{1}{2}} cos (t^{\frac{1}{2}}) + sin (t^{\frac{1}{2}}))

Add a constant to the solution

= 2 (- t^{\frac{1}{2}} cos (t^{\frac{1}{2}}) + sin (t^{\frac{1}{2}})) + C

\int \frac{x ^{3} + x + 5}{x ^{2} + 2 x + 2} d x

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

\int \frac{1}{x 49 x ^{2} - 36} d x

\int t^{2} - 1 d x

\int \frac{2}{x 4 - x ^{2}} d x
