在解答分式问题时,有时候只要转换一下视角,就会体会到“山重水复疑无路,柳暗花明又一村”的奇妙境界.在下面问题中,友情出演的“k”先生,就是这种奇妙体验的主导者.一、“k”先生现射例1已知(a+b)/c=(b+c)/a=(a+c)/b=k,求k/(k~2+1)的值.分析:只要求出k的值就可以了.由已知条件可 When answering fractional questions, sometimes you just have to switch perspectives and you’ll realize the fantastic realm of mountains and rivers, Mr., is the leader of this wonderful experience. First, “k ” Mr. Example 1 is known (a + b) / c = (b + c) / a = (a + c) / b = k , Find the value of k / (k ~ 2 +1) Analysis: As long as the value of k can be obtained by the known conditions can be
