Ways to Construct Equations to Solve Triangular Problems Marin (Affiliated to Anhui Normal University Fuzhong 241001) When dealing with certain trigonometric problems, an equation can be conceived based on the structural features of the topic. With knowledge of equations, problems can often be subtlely solved. This article attempts to make a study of its conceptual approach. First, as a letter (or number) is unknown in the equation construction equation example 1 verification (Fifth International Olympia...
