认识数学的最好方法是做数学,操作实验、思考想象是数学教与学的必由之路[1].如果一味做题而不思考,就会被题目牵着鼻子走,失去主见,变得迷惑而无所得;如果一味空想却不实实在在地做题钻研,则终究是沙上建塔,一无所得.只有把做题和思考结合起来,做到做题后有反思,反思后再做题,才能提高解题能力,发展各种思维策略,加深对数学本质的理解.题1(2011年浙江高考理科18题)在△ABC中,角A,B,C所对的边分别为a,b,c.已知sinA+
The best way to get acquainted with mathematics is to do math, manipulate experiments, and imagine that imagination is the only way to teach and learn math.1 If you blindly think and do not think about it, you will be led by the subject, losing your mind and becoming confused No gain; if blindfolded but not real problem-solving study, after all, the building of the tower on the sand, nothing. Only by combining questions and think together to do after reflection, do reflection In order to improve the ability to solve problems, the development of a variety of thinking strategies to deepen the understanding of the nature of mathematics.Question 1 (2011 College Entrance Examination Zhejiang 18 subjects) in △ ABC, angle A, B, C on the sides were a, b, c. Known sinA +
