expand (x^2+1)(-xsin(x)+2cos(x))

expand

(x^{2} + 1) (- x sin (x) + 2 cos (x))

- x^{3} sin (x) + 2 x^{2} cos (x) - x sin (x) + 2 cos (x)

Solution steps

(x^{2} + 1) (- x sin (x) + 2 cos (x))

Apply FOIL method

(x^{2} + 1) (- x sin (x) + 2 cos (x)) : - x^{3} sin (x) + 2 x^{2} cos (x) - x sin (x) + 2 cos (x)

= - x^{3} sin (x) + 2 x^{2} cos (x) - x sin (x) + 2 cos (x)

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

(5 cos (x) - cos (5 x)) (5 cos (x) - 5 cos (5 x))

(- \frac{5}{6}, - \frac{3}{2}) y (\frac{11}{2}, \frac{1}{3})

- 2 (x^{2} + 2Δ x^{2} + Δ^{2} x^{2}) + 1

(y - 3) (y + 23)
