diffquot f=((f(x+h)-f))/h

解答

差集 quotient

f = \frac{( f ( x + h ) - f )}{h}

\frac{f}{h}

求解步骤

The difference quotient of

f (x)

is given by

\frac{f ( x + 0 ˘ 394 ) - f ( x )}{0 ˘ 394}

用

x + \overset{˘}{0} 394

替代

x

f (x + \overset{˘}{0} 394) = \frac{( f ( ( x + 0 ˘ 394 ) + h ) - f )}{h}

= \frac{\frac{( f ( ( x + 0 ˘ 394 ) + h ) - f )}{h} - \frac{( f ( x + h ) - f )}{h}}{0 ˘ 394}

化简

\frac{\frac{( f ( ( x + 0 ˘ 394 ) + h ) - f )}{h} - \frac{( f ( x + h ) - f )}{h}}{0 ˘ 394} : \frac{f}{h}

= \frac{f}{h}

\frac{f}{h}
