锐角三角函数的求解具有较强的灵活性,只要掌握了求解的规律,求解将不会再困难.首先,锐角三角函数的求解一般要用定义,也就是说要在直角三角形中解决问题.其次,锐角三角函数值是直角三角形边的比值,也就是说最好知道边的长度.因此,勾股定理经常会用到.1.紧紧抓住相应的直角三角形的边长的比 As long as the law of solving is mastered, the solution will not be difficult.Firstly, the definition of trigonometric trigonometric function is generally defined, that is to say, the problem should be solved in right-angled triangle. , Acute trigonometric function value is the ratio of the right triangle edge, which means that the best known edge length. Therefore, the Pythagorean theorem will often be used .1. Grasp the edge of the corresponding right-angled triangle length ratio
