integral of isin(x)

\int i sin (x) d x

- i cos (x) + C

Solution steps

\int i sin (x) d x

Take the constant out:

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

= i \cdot \int sin (x) d x

Use the common integral:

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

= i (- cos (x))

Simplify

= - i cos (x)

Add a constant to the solution

= - i cos (x) + C

\int sin (x + 4) d x

\int \frac{3}{( x ^{2} - 1 )} d x

\int \frac{1}{2} x cos (- 3 x^{2} + 8) d x

\int - 0.8 x + 40 d x

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