\frac{d}{d x} ((x + 1) sin (x)) - x cos (x)

\frac{d}{d x} (x sin (x) + sin (x)) - x cos (x)

求解步骤

\frac{d}{d x} ((x + 1) sin (x)) - x cos (x)

乘开

(x + 1) sin (x) : x sin (x) + sin (x)

= \frac{d}{d x} (x sin (x) + sin (x)) - x cos (x)

e x p an d (e + e^{t})^{2} + (ln (t) + 1)^{2} + 4 t^{2}

e x p an d \frac{( x ^{3} )}{( 2 ( x + 1 ) ^{2} )}

e x p an d \frac{s ^{2}}{( x + 2 ) ( x + 3 )}

e x p an d (y = - \frac{7}{10} + 7) \cdot 10

e x p an d - \frac{6 x ^{2} - 21 x + 50}{( 3 x - 5 ) ( 2 x ^{2} + 5 )}
