當次代數不斷的往上升，，所得的值也會相較之下越來越接近理想中的最大值38.8~所以次代數越多次，所得的值也相較越精確。找最大值-When the algebraic continued to rise, the value of the proceeds will be compared more and more close to the ideal in the algebraic maximum 38.8 ~ So the more times, compared with values obtained from the more accurate. Find the maximum!!
