integral of y^2sin(8y)

\int y^{2} sin (8 y) d y

- \frac{1}{8} y^{2} cos (8 y) + \frac{1}{256} (8 y sin (8 y) + cos (8 y)) + C

Solution steps

\int y^{2} sin (8 y) d y

Apply Integration By Parts

: - \frac{1}{8} y^{2} cos (8 y) - \int - \frac{1}{4} y cos (8 y) d y

= - \frac{1}{8} y^{2} cos (8 y) - \int - \frac{1}{4} y cos (8 y) d y

\int - \frac{1}{4} y cos (8 y) d y = - \frac{1}{256} (8 y sin (8 y) + cos (8 y))

= - \frac{1}{8} y^{2} cos (8 y) - (- \frac{1}{256} (8 y sin (8 y) + cos (8 y)))

Simplify

= - \frac{1}{8} y^{2} cos (8 y) + \frac{1}{256} (8 y sin (8 y) + cos (8 y))

Add a constant to the solution

= - \frac{1}{8} y^{2} cos (8 y) + \frac{1}{256} (8 y sin (8 y) + cos (8 y)) + C

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

x \to 0 - lim (\frac{e ^{- x}}{x ( x + 2 ) ^{2}})

(x + x) \frac{d y}{d x} = y + y

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

f (x) = 6 sec (x), at x = \frac{π}{3}
