我们在解决一些生疏的、复杂的数学问题时,如果不仔细审题,冒然下手,就会让解题过程变得复杂繁琐甚至思维受阻;或者觉得题目条件太少,难以捉摸.实际上如果我们能够更加重视审题,能够对题干进行深入的、细致的、透彻的观察,就不仅能从表面形式上发现特点,而且还能依据题目的具体特征,发现其隐蔽条件,从而使解法得以简化.下面举例说明.例1(2015年江苏高考题)在平面直角坐标系xOy中,以点(1,0)为圆心且与直线mx When we solve some unfamiliar and complicated math problems, we can make the problem solving process more complex and inconvenient if we do not scrutinize or take the trouble, or if we think the problem conditions are too few and elusive, in fact, if we Can pay more attention to examining questions, and can carry out in-depth, meticulous and thorough observation of the subject, not only discover the characteristics from the surface form, but also find the hidden conditions according to the specific characteristics of the subject so as to simplify the solution. Example 1 (Jiangsu 2015 entrance exam) Cartesian coordinate system xOy, the point (1,0) as the center of the circle and the line mx
