0.2707065 (\frac{1}{π} arctan (\frac{0.15}{x}) + 0.5)

\frac{0.2707065}{π} arctan (\frac{0.15}{x}) + 0.13535325

求解步骤

0.2707065 (\frac{1}{π} arctan (\frac{0.15}{x}) + 0.5)

使用分配律:

a (b + c) = ab + a c

a = 0.2707065, b = \frac{1}{π} arctan (\frac{0.15}{x}), c = 0.5

= 0.2707065 \cdot \frac{1}{π} arctan (\frac{0.15}{x}) + 0.2707065 \cdot 0.5

化简

0.2707065 \cdot \frac{1}{π} arctan (\frac{0.15}{x}) + 0.2707065 \cdot 0.5 : \frac{0.2707065}{π} arctan (\frac{0.15}{x}) + 0.13535325

= \frac{0.2707065}{π} arctan (\frac{0.15}{x}) + 0.13535325
