解答

展开

e^{2 t} t^{\frac{1}{5}} + t u (t - 4)

e^{2 t} t^{\frac{1}{5}} + t^{2} u - 4 t u

求解步骤

e^{2 t} t^{\frac{1}{5}} + t u (t - 4)

乘开

t u (t - 4) : t^{2} u - 4 t u

= e^{2 t} t^{\frac{1}{5}} + t^{2} u - 4 t u

e x p an d cot (a) (sin (a) + tan (a))

e x p an d \frac{2 ( s ^{2} + 1 )}{s ^{2} ( s ^{2} + 5 )}

e x p an d \frac{5 ( 5 t ^{2} - 1 ) ^{4} ( 100 t - 5 t ^{2} - 1 )}{( 10 - t ) ^{6}}

e x p an d sin (t) - sin (t) (u) (t - 2 π)

e x p an d 2 cos (2) (x - \frac{π}{3}) - 1
