在三角函数中的配偶是指在某些含有三角函数的代数式中,给它配上一对称的三角代数式(一般指正弦和余弦之间的配偶),在运用配偶法时要求熟练地掌握各个公式,再用它来解就会取得事半功倍的效果,请看下面例题。 A spouse in a trigonometric function means that in some algebraic formulas that contain a trigonometric function, it is assigned a symmetric triangular algebraic formula (usually referred to as the sine and cosine between spouses). When using a spouse method, it is required to master the various formulas. , And then use it to solve it will get twice the result with half the effort, please see the following example.
