In Exercises 55,use a graphing utility to graph f and g in the same viewing window to verify that the two functions are equal.Explain why they are equal.Identify any asymptotes of the graphs.55.f(x)=sin(arctan2x),g(x)=2x/(1+4x^2)^(1/2)
答
在练习55 ,用绘图事业,以图f和g在同一观景窗,以核实这两项职能是平等的.解释为什么他们是平等的.找出任何渐进的图表. 55 .函数f ( x ) =单( arctan2x ) , g ( x )的= 2倍速/ ( 1 +4 χ ^ 2 ) ^ ( 1 / 2 )
