解答

展开

\frac{n T}{s ( R ( M + n ^{2} J ) s + TB )}

\frac{n T}{s ^{2} RM + n ^{2} s ^{2} R J + T s B}

求解步骤

\frac{n T}{s ( R ( M + n ^{2} J ) s + TB )}

乘开

R (M + n^{2} J) s + TB : s RM + n^{2} s R J + TB

= \frac{n T}{s ( s RM + n ^{2} s R J + TB )}

乘开

s (s RM + n^{2} s R J + TB) : s^{2} RM + n^{2} s^{2} R J + T s B

= \frac{n T}{s ^{2} RM + n ^{2} s ^{2} R J + T s B}

e x p an d 10 x - (2 x + 9 = - 3 (15 - 4 x))

e x p an d - \frac{4 ( 11 + 341 )}{11}

e x p an d - 2 cos (0.5 (x - 7.3))

e x p an d \frac{g ( 4 x + 1 )}{f ( 3 x ^{2} )}

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