本刊’94第12期《巧求函数y=Asin(ωx+)图象的对称轴》一文,给出了y=Asin(ωX+)的对称轴的一种巧妙求法,这里将利用其对称轴给出一道常见习题的巧妙解法.
In the article ’94 Issue 12 of the symmetry axis of the function y=Asin(ωx+) image, a dexterous solution to the symmetry axis of y=Asin(ωX+) is given. Here it will use its symmetry. The axis gives a clever solution to a common problem.
