化简-1.5(cos(0.25t^2)-0.5t^2sin(0.25t^2))

解答

化简

- 1.5 (cos (0.25 t^{2}) - 0.5 t^{2} sin (0.25 t^{2}))

- 1.5 cos (0.25 t^{2}) + 0.75 t^{2} sin (0.25 t^{2})

- 1.5 (cos (0.25 t^{2}) - 0.5 t^{2} sin (0.25 t^{2})) : - 1.5 cos (0.25 t^{2}) + 0.75 t^{2} sin (0.25 t^{2})

= - 1.5 cos (0.25 t^{2}) + 0.75 t^{2} sin (0.25 t^{2})

e x p an d \frac{( a + bi ) ^{6}}{( a - bi ) ^{2}}

e x p an d (cos (ln (x)) + sin (ln (x)))^{2}

e x p an d (1 - \frac{1 - cos ( x π )}{2}) 1 0^{\frac{x}{2}}

e x p an d \frac{1}{8} e^{4 x} (- 4 e^{- 4 t} t - e^{- 4 t})

e x p an d 2 cos (5) (2 tan (5) x + 25)
