关于三角函数有理式积分的探讨

On Trigonometric Function Rational Integral

三角函数有理式积分在积分的计算中占有很重要的地位 ,且计算较为复杂 ,属教学中难点。本文就一类三角函数有理式的积分的特殊性及一般性进行探讨 ,特殊性给出一题多解 ,一般性推出求解公式。

Trigonometric Function Rational Integral plays an important role in the calculation of integral, with a little bit complicated calculating way, belonging to the difficulty in teaching. This paper discusses from two aspects: the special way, one with more solutions and the general way—offering solution formula.
