化简 (g\circ i+i/g)(x)

解答

化简

(g \circ i + \frac{i}{g}) (x)

i \frac{x + \circ g ^{2} x}{g}

求解步骤

(g \circ i + \frac{i}{g}) (x)

去除括号:

(a) = a

= (g \circ i + \frac{i}{g}) x

将

(g \circ i + \frac{i}{g}) x

改写成标准复数形式:

\frac{\circ g ^{2} x + x}{g} i

= \frac{\circ g ^{2} x + x}{g} i

e x p an d \frac{( x + 8 ) ( 3 x + 4 )}{( 4 x - 5 )}

e x p an d \frac{( a + c ) ^{2}}{b}

e x p an d \frac{( - 7 x + 630 ) ^{2}}{900}

e x p an d \frac{( 27 - y ) ^{2}}{2}

e x p an d π (4 - 2 x)^{2} d x
