化简 y(t/5-(sin(5t))/(25))

解答

化简

y (\frac{t}{5} - \frac{sin ( 5 t )}{25})

\frac{y ( 5 t - sin ( 5 t ) )}{25}

求解步骤

y (\frac{t}{5} - \frac{sin ( 5 t )}{25})

化简

\frac{t}{5} - \frac{sin ( 5 t )}{25} : \frac{5 t - sin ( 5 t )}{25}

= y \frac{5 t - sin ( 5 t )}{25}

使用分式法则:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{y ( 5 t - sin ( 5 t ) )}{25}

e x p an d \frac{2}{3 ( 12 x ^{2} - 15 x - 24 )}

e x p an d (x - 5) (2 - x - x + 4)

e x p an d (6 - 3 x^{2}) e^{x} - 6 x e^{x}
