展开 T(p(x)=2p(x)-p(2x))

解答

展开

T (p (x) = 2 p (x) - p (2 x))

Tp (x) = 2 p (x) - Tp (2 x)

求解步骤

T (p (x) = 2 p (x) - p (2 x))

= T (2 = p (x) p (x) - p (2 x))

使用分配律:

a (b - c) = ab - a c

a = T, b = p (x) = 2 p (x), c = p (2 x)

Tp (x) = 2 p (x) - Tp (2 x)

e x p an d 0.015 \cdot (3.44 - 106.4 x + 867 x^{2} - 1264 x^{3})^{2}

e x p an d 2584.72 \cdot (x + y - 0.08)^{2}

e x p an d a (1, 2) + b (3, - 1)

e x p an d \frac{( x \cdot ln ( x ^{2} + 1 ) )}{( x ^{2} + 1 ) ^{3}}

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