expand x^2sin(x)-2(-xcos(x)+sin(x))

expand

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

\frac{x ^{2} - 2}{csc ( x )} + 2 x cos (x)

Solution steps

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

Expand

- 2 (- x cos (x) + sin (x)) : 2 x cos (x) - 2 sin (x)

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

Rewrite using trig identities

= \frac{x ^{2} - 2}{csc ( x )} + 2 x cos (x)

\frac{( a + b ) ^{2}}{4}

(x - \frac{9}{2})^{2}

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

2 (e^{2} - 1)

y d x - 2 (x + y) d y
