摘要
学生在数学写作中经常犯错误,尤其是在三角函数角度的数学表达式写作中。造成这种错误的原因之一是学生在写问题或写答案时没有密切注意弧度和度数的区别。这些数学写作错误主要是由学生以问题的答案结果为导向,而不注意良好和正确的写作规则造成的。三角函数数学表达式中的一种书写错误形式是将y = sin (x + 45)写成y = sin (x + 45),这被认为与y = sin (x + 45)相同。如果让他们在同一幅图中比较两个数学表达式的函数的图形形式,就会发现书写错误。数学学习中的反例和技巧可以帮助学生理解和纠正三角函数数学表达式的书写错误。
ANALYSIS OF MATHEMATICAL WRITING ERRORS RELATED TO THE ANGLE OF TRIGONOMETRI FUNCTIONS
Mathematical writing errors are often made by students, especially when writing mathematical expressions on the angle of trigonometric functions. One of the causes of this error is that students do not pay close attention to the difference between radians and degrees when writing questions or writing answers. These mathematical writing errors were made mainly by students who were oriented towards the result of the answer to a question, without paying attention to good and correct writing rules. One form of writing errors in mathematical expressions of trigonometric functions is writing y = sin (x + 45), which is considered the same as writing y = sin (x + 45o). If they are asked to compare the graphical form of the function of the two mathematical expressions in the same image, the writing error will be recognized and seen. Counterexamples and technology in learning mathematics can help students understand and correct errors in writing mathematical expressions of trigonometric functions.
