integral of sin(x)cos(n)x

\int sin (x) cos (n) x d x

cos (n) (- x cos (x) + sin (x)) + C

Solution steps

\int sin (x) cos (n) x d x

Take the constant out:

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

= cos (n) \cdot \int sin (x) x d x

Apply Integration By Parts

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

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

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

= cos (n) (- x cos (x) - (- sin (x)))

Simplify

= cos (n) (- x cos (x) + sin (x))

Add a constant to the solution

= cos (n) (- x cos (x) + sin (x)) + C

y^{^{'}} = \frac{t}{1 + t ^{2}} \cdot e^{y}

n \to \infty lim (\frac{x}{n})

\frac{d}{d r} (\frac{1}{r ^{2}})

\frac{1}{3} x^{- \frac{2}{3}}

\int sin^{3} (v) cos^{8} (v) d v
