integral of y^2*cos(y)

\int y^{2} \cdot cos (y) d y

y^{2} sin (y) - 2 (- y cos (y) + sin (y)) + C

Solution steps

\int y^{2} cos (y) d y

Apply Integration By Parts

= y^{2} sin (y) - \int 2 y sin (y) d y

\int 2 y sin (y) d y = 2 (- y cos (y) + sin (y))

= y^{2} sin (y) - 2 (- y cos (y) + sin (y))

Add a constant to the solution

= y^{2} sin (y) - 2 (- y cos (y) + sin (y)) + C

\int \frac{5}{2 x - 2} d x

x \to 1 + lim (\frac{x}{ln ( x )})

x \to 3 lim (x^{2} + x - 5)

y^{^{''}} - (\frac{x}{x - 1}) y^{^{'}} + \frac{1}{x - 1} y = 0

x \to 2 lim (3 x^{2} + 2 x - 16)
