解答

展开

1 + sin (b) (12, - 9)

1 + 12 sin (b), - 9 sin (b)

求解步骤

1 + sin (b) (12, - 9)

= 1 + (12, - 9) sin (b)

乘开

sin (b) (12, - 9) : 12 sin (b), - 9 sin (b)

= 1 + 12 sin (b), - 9 sin (b)

e x p an d \frac{( x - 3 ) \cdot ( 25 \cdot x - 75 )}{2}

e x p an d \frac{1}{( t ^{2} - 9 ) ^{2}}

e x p an d \frac{270000 \cdot 0.05}{1 - ( 1 - 9 ) ^{- 60}}

e x p an d \frac{C ( 2 ^{X} + 3 ^{X} )}{6 ^{X}}

e x p an d x^{n + 1} (x^{n} + 3) + x^{n} (x^{3} - 1)^{'}
