刚接触TI图形计算器时 ,我没有想到TI图形计算器的功能如此之大 ,它不仅能够作函数图象 ,显示函数值表 ,而且还能够解决数列、统计、金融等实际问题 .TI图形计算器为探索、发现、猜想、验证等数学实验提供了环境 ,为我学习数学提供了很大的帮助 ,我从此对数学产生了浓厚的兴趣 When I first touched TI’s graphing calculator, I didn’t expect that TI’s graphing calculator would be so powerful that it could not only function as a function image, but also display function value tables, and it could also solve practical problems such as series, statistics, and finances. The instrument provided an environment for mathematical experiments such as exploration, discovery, conjecture, and verification. It helped me learn mathematics, and I have had a keen interest in mathematics since then.
